/** LedPwmOutCC class
 *
 *  @class LedPwmOutCC
 *
 *  "LedPwmOutCC" class works like "PwmOut" class of mbed-SDK. 
 *  This class provides API on device's pin level with abstracting the LED controller. 
 *
 *  Example:
 *  @code
 *  #include "mbed.h"
 *  #include "PCA9956A.h"
 *  
 *  PCA9956A    led_cntlr( p28, p27, 0xC4 );  //  SDA, SCL, Slave_address(option)
 *  LedPwmOutCC led( led_cntlr, L0 );
 *  
 *  int main()
 *  {
 *      while( 1 ) {
 *          for( float p = 0.0f; p < 1.0f; p += 0.1f ) {
 *              led     = p;
 *              wait( 0.1 );
 *          }
 *      }
 *  }
 *  @endcode
