*
************************************************************************
*
* The motivation for this wrapper is to avoid issues where you need to
* decode both FLAC and Ogg FLAC but don't want to enclose all of your code
* in enormous if blocks where the body of the two branches is essentially
* the same. For example, you don't want to do something like this:
*
* if (is_ogg_flac)
* {
* OggFLAC__blah_blah();
* OggFLAC__more_stuff();
* }
* else
* {
* FLAC__blah_blah();
* FLAC__more_stuff();
* }
*
* when you really just want this:
*
* EasyFLAC__blah_blah();
* EasyFLAC__more_stuff();
*
* This is even more cumbersome when you have to deal with constants.
*
* EasyFLAC uses essentially the same API as
* FLAC__stream_decoder with two additions:
*
* - EasyFLAC__is_oggflac() for those rare occassions when you might
* need to distiguish the difference cases.
*
* - EasyFLAC__stream_decoder_new() takes a parameter to select when
* you are reading FLAC or Ogg FLAC.
*
* The constants are all FLAC__stream_decoder_*.
*
