Update the GetUnits method to accept start/stop instead of start/num

Description

Right now the GetUnits method (for the FAT DataLayer) accepts the first sector and a number of sectors to retrieve. Change this (and the super classes) to accept a start and stop sector (inclusive and non-inclusive respectively) instead.

This needs to be implemented prior to the 0.4beta release
