1. faster exclusions:

		keep a global counter Exclude_Counter
		increment it prior to each byte.
		don't clear the exclude mask ever (this is where the savings are)
		to exclude, set ExcludeMask[c] = Exclude_Counter
		to test exclusion test ( ExcludeMask[c] == Exclude_Counter )

2. tune constants in ppmz_cfg.c and ppmdet.c

3. LOE needs to include PPMdet & order0 , as does UpdateC

4. faster PPMdet string matching (!?)

5. MTF good or not?

6. use ->NumItemsActive in FreePool to report Total Memory Used

7. better RunTrans settings that don't kill 'pic'
		EncodeCDone_Min() in RT

8. lower ScaleDown than 32000 ? in Order0 ?
