Base abstract class for Gesture Recognizers. For internal use only. Gesture recognizers listen to events that occur on a target object to see if a particular gesture has occurred. Recognizer-specific configuration values can be modified through @.config. Default configuration values are taken from the system's configuration. - (M) add - (M) recognize - (M) reset - (P) config
