I'm not sure that anyway has actually confirmed that using TIP4P
in CHARMM gives to correct properties, though people are working
on this. If I get additional information I'll post it. Concerning TIP5P,
it has also not yet been implemented, although it should function.
Again, I'll post info as it comes in.
