/**
 * Sends a String of data to the Mac OSX Buffer, this is very helpful if 
 * you are doing something in scratch pad and want to copy it somewhere.
 * 
 * this beats Pipe-ing the output to pbcopy directly. 
 *
 * @param {string} data - Required UTF-8 String to be copied to the buffer.
 *
 * @return {void}
 *
 * @example
 * pbcopy(JSON.stringify(data, null, 4))
