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.
