first pass at converting EXTMatrix.m to use NSMutableData
large-scale changes to move EXTMatrix from using NSMutableArray to NSMutableData. first build with no compile-time issues.
fixed a bunch of minor errors, mostly stemming from NSArray not tracking the types of objects it contains. there’s still a major error lurking about.
fix another type error in the move to NSMutableData
use -appendData rather than manually using memcpy
corrects a couple of array to data translation errors
fixes bugs preventing multiplication annotations from displaying properly. (still something funny about the -reloadData call being issued, but that’s cosmetic.)
fixes the -reloadData issue @_@
increment the file version number; we can’t load old charts with such a dramatic change.
fix a characteristic bug
corrects a bad iterator upper bound, fixes multiplication annotation drawing.
