+/* mbed PwmIn Library UPDATED 
+ * Copyright (c) 2008-2010, sford
+ *------------------------------------------------------------------------------
+ *Rise and Fall libraries were giving  warning: "mbed::InterruptIn::rise(T *, M) 
+ *[with T=PwmIn, M=void (PwmIn::*)()] was declared deprecated". As of that ,
+ *I updated the code with the proper functions.
+ *_p.rise(this, &PwmIn::rise); changed with _p.rise(callback(this, &PwmIn::rise));
+ *_p.fall(this, &PwmIn::rise); changed with _p.fall(callback(this, &PwmIn::rise));
+ *I also changed some methods names  beacause I think they could generate some 
+ *confusion while progamming together with PwmOut.
