[Mmcdtools-discuss] New log format

[Clinton B. <cba...@la...>]

Reworking structs inside MMCd to simplify adding new sensor types.

Each sensor will include:
  Short Tag
  Long Tag
  Units
  HWChan     (ECU / expansion register)
  FSCount     (255, 1023, 8191 etc)
  Decimal     (number of digits to display)
  Interpolate (0 if no interpolation, otherwise ID of interpolation table)
  Scale
  Offset
  GrMin
  GrMax
This will eliminate a fair amount of redundant scaling code and simplify
adding new sensors. Same struct will be prepended to beginning of each log
to elminate hard coding of scaling info in MMCdTools.

Plan of attack on MMCdTools (to maintain backward compatibility) is to
detect "headerless log files" and use a default header structure.

Design decision on MMCd logger that I am still wrestling with is whether to
add support for > 32 active sensors or just allow up to 32 sensors to be
selected from a larger pallet.
