File operations (SD card)

These functions are implemented in versions of BASIC for the DataLogger and Teensy3.0/3.1.  Other versions on Coridium boards are currently under development.

The current version limits the use to having only 1 file open at a time, and only operations in the root directory. File names are limited of up to 8 characters period followed by up to 3 characters. Spaces are NOT allowed in filenames.
