unicodejs.graphemebreak.js * New file: singleton class with splitClusters method * On load, builds graphemeBreakRegexp from unicodejs.graphemebreakproperties.js unicodejs.js * Remove old splitClusters method (was just a placeholder) * Change "conjunction" -> "disjunction", for consistency and correctness unicodejs.textstring.js * Use new splitClusters method modules/ve/ve.js * Use new splitClusters method unicodejs.wordbreak.text.js * Add new splitClusters test * Refactor charRangeArrayRegexp test to use splitClusters PHP files * add unicodejs.graphemebreak.js, unicodejs.graphemebreakproperties.js .docs/categories.json * add unicodeJS.wordbreak class Change-Id: I8f512e2fc2c46eb4b5f00994a8dac88f3c8f7dd2
