Web assets processor. Native JavaScript port of Sprockets.

/**
 *  class SafetyColons
 *
 *  For JS developers who are colonfobic, concatenating JS files using
 *  the module pattern usually leads to syntax errors.
 *
 *  The `SafetyColons` processor will insert missing semicolons to the
 *  end of the file.
 *
 *  This behavior can be disabled with:
 *
 *      environment.unregisterPostProcessor('application/javascript', SafetyColons);
 *
 *
 *  ##### SUBCLASS OF
 *
 *  [[Template]]
