'patch' didn't like any of these patches, since none of them ended in a
CR. So I had to add that in manually. May be worth checking at your end
to see what's stripping the terminating CR, since 'svn di' doesn't
usually do that...

Looks fine to me: r339.
The next updates the nonbonded list in two ways. First it is refactored
so that the internals can be reused by other states (namely a
BipartiteNonbondedListState I use) and secondly the distance threshold
belongs in the iterator, not in the constructor as different restraints
may have different thresholds. It is not currently used as the internal
implementation is dumb, but we should try to converge on the desired
interface anyway.
I committed this as r340, but I don't agree 100% on the second point.
One of the major advantages of a nonbonded list is that the evaluation
time scales (typically) as NlogN rather than N^2, because it does not
contain all pairs of atoms in the system once the system 'box' size
increases past the cutoff. Of course with the existing implementation
this makes no difference, but with a smarter implementation we'd
probably want a cutoff both in the constructor and in the iterators
(with a simple condition that the constructor cutoff is not less than
any iterator cutoff).
Corresponding changes are made to the NonbondedRestraint
Same comment above applies; r341.
I added a preliminary implementation of a BondedList which uses the bond
decorator definition of a bond. It comes with a restraint which uses
length and spring constant info stored in the bond particle to restrain
the bond. We probably want to revisit what is stored in the bond (in
light of the discussions concerning the Harmonic).
Tragically you forgot to include BondDecoratorRestraint.cpp...
Finally, the aforementioned bipartite nonbondedlist. It only returns
pairs which cross two sets of particles. It seemed worth having such a
class as it can be implemented much more efficiently than just having
filters on top of the regular nonbonded list. And it is little code
until then.
