 * CallTipsHandler.
 * 
 * Code which responds to a calltip request by:
 * 
 * 1) Searching for the signature name.
 * 2) Displaying it as a calltip under the prospective method.
 * 
 * A calltip request occurs when a user enters:
 * 
 * 		"method(" or "class.method(" or "self.method("
 * 
 * in the editor (an action listener will be put in place).
 * 
 * On tab press, if the tip is currently visible, the cursor is jumped
 * over to the next parameter in the signature.
