Optimize screen visibility checks during search

When 'Search whole file' is disabled, search results are tested for visibility on the screen. There is already an optimization that only checks results on visible lines, but the number of offset-to-XY conversions still scales linearly with the number of results, which can be very large in files with long lines.

A simple observation is that every line has a first and last offset that is visible on the screen (which may be different for each line due to proportional fonts).

This commit caches the visible offset range for every line involved in one search query, so testing visibility of a search result becomes a check if its offset is inside its line's visible offset range. Finding the visible offset range requires two XY-to-offset conversions per line, so the total number of conversions is bounded by the number of lines that can fit on the screen.

The worst case for this optimization is when every line has exactly one search result; before, this would lead to one offset-to-XY conversion per line, whereas now it leads to two XY-to-offset conversions per line. However, the maximum number of conversions is twice the number of visible lines, which will generally be very small.

 *Miscellaneous: AceJump is built using [Gradle](https://gradle.com/) with the [Gradle Kotlin DSL](https://docs.gradle.org/5.1/userguide/kotlin_dsl.html) and the [gradle-intellij-plugin](https://github.com/JetBrains/gradle-intellij-plugin).*
 
+## Extending
+
+AceJump can be used by other [IntelliJ Platform](https://plugins.jetbrains.com/docs/intellij/welcome.html) plugins. To do so, add the following snippet to your `build.gradle.kts` file:
+
+```kotlin
+intellij {
+  plugins.set("AceJump:<LATEST_VERSION>")
+}
+```
+
+Callers who pass an instance of [`Editor`](https://github.com/JetBrains/intellij-community/blob/master/platform/editor-ui-api/src/com/intellij/openapi/editor/Editor.java) into `SessionManager.start(editor)` will receive a [`Session`](src/main/kotlin/org/acejump/session/Session.kt) instance in return. Sessions are disposed after use.
+
+To use AceJump externally, please see the following example:
+
+```kotlin
+import org.acejump.session.SessionManager
+import org.acejump.session.AceJumpListener
+import org.acejump.boundaries.StandardBoundaries.*
+import org.acejump.search.Pattern.*
+
+val aceJumpSession = SessionManager.start(editorInstance)
+
+aceJumpSession.addAceJumpListener(object: AceJumpListener {
+  override fun finished() {
+    // ...
+  }
+})
+
+// Sessions provide these endpoints for external consumers:
+
+/*1.*/ aceJumpSession.markResults(sortedSetOf(/*...*/)) // Pass a set of offsets
+/*2.*/ aceJumpSession.startRegexSearch("[aeiou]+", WHOLE_FILE) // Search for regex
+/*3.*/ aceJumpSession.startRegexSearch(ALL_WORDS, VISIBLE_ON_SCREEN) // Search for Pattern
+```
+
+Custom boundaries for search (i.e. current line before caret etc.) can also be defined using the [Boundaries](src/main/kotlin/org/acejump/boundaries/Boundaries.kt) interface.

-#   Gradle start up script for POSIX generated by Gradle.
-#
-#   Important for running:
-#
-#   (1) You need a POSIX-compliant shell to run this script. If your /bin/sh is
-#       noncompliant, but you have some other compliant shell such as ksh or
-#       bash, then to run this script, type that shell name before the whole
-#       command line, like:
-#
-#           ksh Gradle
-#
-#       Busybox and similar reduced shells will NOT work, because this script
-#       requires all of these POSIX shell features:
-#         * functions;
-#         * expansions «$var», «${var}», «${var:-default}», «${var+SET}»,
-#           «${var#prefix}», «${var%suffix}», and «$( cmd )»;
-#         * compound commands having a testable exit status, especially «case»;
-#         * various built-in commands including «command», «set», and «ulimit».
-#
-#   Important for patching:
-#
-#   (2) This script targets any POSIX shell, so it avoids extensions provided
-#       by Bash, Ksh, etc; in particular arrays are avoided.
-#
-#       The "traditional" practice of packing multiple parameters into a
-#       space-separated string is a well documented source of bugs and security
-#       problems, so this is (mostly) avoided, by progressively accumulating
-#       options in "$@", and eventually passing that to Java.
-#
-#       Where the inherited environment variables (DEFAULT_JVM_OPTS, JAVA_OPTS,
-#       and GRADLE_OPTS) rely on word-splitting, this is performed explicitly;
-#       see the in-line comments for details.
-#
-#       There are tweaks for specific operating systems such as AIX, CygWin,
-#       Darwin, MinGW, and NonStop.
-#
-#   (3) This script is generated from the Groovy template
-#       https://github.com/gradle/gradle/blob/HEAD/subprojects/plugins/src/main/resources/org/gradle/api/internal/plugins/unixStartScript.txt
-#       within the Gradle project.

+ * Solves the Tag Assignment Problem. The tag assignment problem can be stated
+ * thusly: Given a set of indices I in document d, and a set of tags T, find a
+ * bijection f: T*⊂T → I*⊂I s.t. d[i..k] + t ∉ d[i'..(k + |t|)], ∀ i' ∈ I\{i},
+ * ∀ k ∈ (i, |d|-|t|], where t ∈ T, i ∈ I. Maximize |I*|. This can be relaxed
+ * to t=t[0] and ∀ k ∈ (i, i+K] for some fixed K, in most natural documents.
+ *
+ * More concretely, tags are typically two-character strings containing alpha-
+ * numeric symbols. Documents are plaintext files. Indices are produced by a
+ * search query of length N, i.e. the preceding N characters of every index i in
+ * document d are identical. For characters proceeding d[i], all bets are off.
+ * We can assume that P(d[i]|d[i-1]) has some structure for d~D. Ultimately, we
+ * want a fast algorithm which maximizes the number of tagged document indices.
+ *
+ * Tags are used by the typist to select indices within a document. To select an
+ * index, the typist starts by activating AceJump and searching for a character.
+ * As soon as the first character is received, we begin to scan the document for
+ * matching locations and assign as many valid tags as possible. When subsequent
+ * characters are received, we refine the search results to match either:
+ *
+ *    1.) The plaintext query alone, or
+ *    2.) The concatenation of plaintext query and partial tag
+ *
+ * The constraint in paragraph no. 1 tries to impose the following criteria:
+ *
+ *    1.) All valid key sequences will lead to a unique location in the document
+ *    2.) All indices in the document will be reachable by a short key sequence
+ *
+ * If there is an insufficient number of two-character tags to cover every index
+ * (which typically occurs when the user searches for a common character within
+ * a long document), then we attempt to maximize the number of tags assigned to
+ * document indices. The key is, all tags must be assigned as soon as possible,
+ * i.e. as soon as the first character is received or whenever the user ceases
+ * typing (at the very latest). Once assigned, a visible tag must never change
+ * at any time during the selection process, so as not to confuse the user.
