Message:

Extended ExportGraph to spill our molecular fragments one by one.

• the biggest scaling issue with fragmentation is the number of hydrogen atoms that are created to saturate all (e.g. 200.000 fragments frm 3.000 atoms at order 6!) the molecular fragments.
• hence, create one by one and have a controlled pool of hydrogens that are re-used.
