decided to go back to memory.factor
change back to use memory.factor
mblock was removed into seperate file
add mblock.factor handles the blocks of memory
git ignore file
hexdump now works with memory routines
new cpu-read-byte needs more work
added routine to return sub portion of the sequence to be used in
hexdump
subseq added and an address to array index routine
add gitignore so we will ignore it
