Better InSty kwarg docs

[jamesmkrieger]

We have multiple options for using kwargs so that we can control individual types of interactions or all of them at once, so I updated the docs accordingly

For example, we can do this. The first change (using distDA) just affects H bonds (first entry) and the second change (using distA) affects all of them.

In [1]: from prody import *

In [2]: PDBfile = 'addH_9asd.pdb'

In [3]: atomsRL = parsePDB(PDBfile).select('protein and chain R L')

In [4]: interactions = Interactions()

In [5]: all_interactions = interactions.calcProteinInteractions(atomsRL)

In [6]: [len(ints) for ints in all_interactions]
Out[6]: [50, 6, 0, 6, 4, 60, 5]

In [7]: all_interactions = interactions.calcProteinInteractions(atomsRL, distDA=4)

In [8]: [len(ints) for ints in all_interactions]
Out[8]: [68, 6, 0, 6, 4, 60, 5]

In [9]: all_interactions = interactions.calcProteinInteractions(atomsRL, distA=4)

In [10]: [len(ints) for ints in all_interactions]
Out[10]: [68, 1, 0, 1, 0, 55, 5]

That is super useful! Thank you.
