Initial commit for re-factoring to read sample-by-sample. Broken if repeat is used, no other parameters tested.  Works for a straight read/write.
More fixes for sample-by-sample reading.  Moving towards a more functional approach, using feof to track the file reading (and hope it works)
Implementing attack for the new approach.  Verified.  Seek also verified.
Looping added and working.
Formatting
Commenting code and cleaning up unused variables
Added timestretch algorithm
Working timestretchtest with sub 50 values, should work for any value now.
Adding TODO text for integrating full timestretch.
Sub-50 timestretch now working, re-factoring granulation loop to account for new sample duplication process.
Adding timestretchtest from sandbox branch.
Initial commit of GRAMPS Arduino code.  Stolen from SimpleAudioPlayer.
US17: Adding initial granulation of test file.
Switching to using SdFat for usage with MicroSD with Due.
Modified for testing without audio.
US14: Switching to correct CS pin
Merge completed US14 branch.
US14: Testing WAV file output successful
US17: Updating for US14 changes
Merge remote-tracking branch 'origin/feature-us17' into projectdev
