/**
* @fileoverview `IgnorePattern` class.
*
* `IgnorePattern` class has the set of glob patterns and the base path.
*
* It provides two static methods.
*
* - `IgnorePattern.createDefaultIgnore(cwd)`
* Create the default predicate function.
* - `IgnorePattern.createIgnore(ignorePatterns)`
* Create the predicate function from multiple `IgnorePattern` objects.
*
* It provides two properties and a method.
*
* - `patterns`
* The glob patterns that ignore to lint.
* - `basePath`
* The base path of the glob patterns. If absolute paths existed in the
* glob patterns, those are handled as relative paths to the base path.
* - `getPatternsRelativeTo(basePath)`
* Get `patterns` as modified for a given base path. It modifies the
* absolute paths in the patterns as prepending the difference of two base
* paths.
*
* `ConfigArrayFactory` creates `IgnorePattern` objects when it processes
* `ignorePatterns` properties.
