XSB Src (SVN)-old

Fixed to print out instr addresses as ptrs, integers dont work well for 64-bits.

Fixed to add is_neg_call

Added these figures, which I had previously forgotten.

added test of sdg_scc_info.

Updated sdg_scc_info/2 which provides summary scc info for an SDG.

Changed bit declarations from unsigned int to byte (unsigned char).
This is more space efficient, but was really done because there is
some issue with MSVC when the unsigned int is used. There must be some
alignment and/or displacement kind of problem with the unsigned int.
I don't have the time/energy/interest to try to track down the exact
reason....sorry.

Fixed typo so that bit-fields carved out of a byte will again add up to 8.

changed documenting comment for crypto_hash

Updated for pos/neg edges and added more test cases.

Support for positive and negative edges in SDG analysis.
