a heap checker.
SEAM and SPLIT have been begging for a refactor for a *LONG* time.
This change does most of the work of turning them into proper classes:
Moved relevant code into SEAM/SPLIT/TBLOB/EDGEPT etc from global helper functions.
Made the splits full data members of SEAM in an array instead of 3 separate pointers.
This greatly reduces the amount of new/delete happening in the chopper, which is the main goal.
Deleted redundant files: olutil.*, makechop.*
Brought other code into SEAM in order to keep its data members private with only priority having accessors.
During our initial chopping for each word, pay attention to whether a
dangerous ambiguity (like rn <-> m) would lead us to a dictionary word.
If so, make sure that blob gets chopped so that we can evaluate said
dictionary word during the segmentation search.
Large accuracy improvement, especially on English printed books (~9%).
