Working sensorboard on pv_module supports logging 3 voltages and a current to a FAT32
formatted SD Card.  FAT32 implementation is quite lean but allows writing to already created
files without changing their size.  Size changing will be added soon as will file creation.

Modified pic12 build system to accomodate larger memory of pic16lf1847.
Updated mib12_executive to support devices with more than 1 code page (i.e. we correctly
protect ourselves against people changing the PCLATH register)
Quick tool for inspecting MIB application record structure in a hex file
Working version 1.0 of pv logging module including process_log.py tool for configuring
and processing the log files generated by the module.
Pic12 executive now with complete page guarding code to handle application modules
that span multiple pages.
Changed default line terminator to be compatible with excel so that there are not blank lines in the imported file.
