/** A subclass of TransposingSamplePlayingInstrument which maps pitches to sound files, and transposes to fill in unmapped gaps,
 * 
 * Does a simple loop to sustain the sample over time.  You will hear a possibly clicky repeat loop.  For smoother sustain, see CelloSampleSustainingIns
 *  
 * Copy and rename this example, change the buildFromAttributes() method.
 * 
 * This example only maps one cello soundfile to middle C, to serve as an example without shipping a huge sample bank.
