assembly listings from yaASM and yaLEMAP. Added some debugging messages to 'make install'. Tweaked debugging messages that VirtualAGC embeds in 'simulate'. Verified buildability in Mint 21, 20, 19, 17, and verified buildability using clang in Mint 17.

Filename: SplitInterp.c
Purpose: This is a little utility that takes a 15-bit word from an
AGC binary executable and splits it apart to see what
interpretive codes it might have included. I am using this
solely for reverse engineering Block 1 interpretive language.
(I must have done something similar for Block 2, but don't
know what it was.)
