+/** LedPwmOut class
+ *
+ *  "LedPwmOut" 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 "PCA9632.h"
+ *  
+ *  PCA9632     led_cntlr( p28, p27, 0xC4 );  //  SDA, SCL, Slave_address(option)
+ *  LedPwmOut   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
