//
//  Summary:  PS_Adafruit_MPR121 is a class which implements the SmartThings
//  "Contact Sensor" device capability.
//  It inherits from the st::InterruptSensor class.
//
//  Create an instance of this class in your sketch's
//  global variable section 			  For Example:
//  st::PS_Adafruit_MPR121 sensor(F("touchButtons"), 5);
//
//	st::PS_Adafruit_MPR121() constructor requires the following arguments
//  - String &name - REQUIRED - the name of the object, should be "touchButtons_Kitchen", "touchButtons_Desk", etc...
//  - int8_t activatedButtonId - REQUIRED - the id of the sensor that is used to activate the touching capability
//  - uint8_t sensibility5C = 0x10, together with sensibility5D sets the sensibility of the touch sensors
//  - uint8_t sensibility5D = 0x20,
//	- long reqNumMillisHeld = 1000 - milliseconds thesholdb between "Held" and "Pushed"
//  - 
//(default = 1000)
//
//  Change History:
//
//    Date        Who            What
