bitbit.sh  for the bit experiment

This script, as it is now, generates all mol files of molecules made of
two “bits”  connected by a pair MULOUT-MULIN.
There are 36 “bits”, therefore the scripts runs foe_bubbles_bit_exp.awk
(a slight modification of foe_bubbles_04_11.awk) for 7 reduction steps
for each generated mol file. Then the file data.txt contains the
results, which consist in name of file and nodes for each iteration, or
other stuff (no of added nodes, trashed nodes, etc), according to small
obvious modifications inside.
