[MMTK] Small energy differences

Hi Konrad and all others,

great that MMTK 2.2 is out. I noticed that minimizing a particular
configuration (two glycine chains in periodic universe with Amber94)
that I get slightly different energies with different versions of MMTK
(2.1b6 and 2.1b9, now I am trying 2.2). The differences are always
smaller than 0.5 kJ/mol, which seems pretty small to me. Is that
something you would expect because of minor changes, or should I look
into this?

Best regards,
