 * Recognizer flow explained; *
 * All recognizers have the initial state of POSSIBLE when a input session starts.
 * The definition of a input session is from the first input until the last input, with all it's movement in it. *
 * Example session for mouse-input: mousedown -> mousemove -> mouseup
 *
 * On each recognizing cycle (see Manager.recognize) the .recognize() method is executed
 * which determines with state it should be.
 *
 * If the recognizer has the state FAILED, CANCELLED or RECOGNIZED (equals ENDED), it is reset to
 * POSSIBLE to give it another change on the next cycle.
 *
 *               Possible
