Added comment to user guide about support for MB85RS64V variant.
Refactored SPI-related code in preparation for new ARM version of library.
Added example program for multiple FRAMs.
Corrected redundant variables in "arraytypes" example program.
Improved structure of example programs.
Changed memory addresses, array indices and array element sizes to support 24-bit addresses.
Added MB85RS1MT and MB85RS2MT to list of supported ICs.
Moved hardware initiation from constructor to begin().
