Extending compatibility of Molecule class instantiation from other file types

[ianrinehart]

As a normal part of doing any computations, a bunch of structures that I was working with had some errors. I could easily get xyz files, triage the problems, and make the necessary edits so that they will work.

Unfortunately, I have xyz files and there is not a clear way to create molecule class instances. If there were, then I would easily be able to reenter the workflow with these "special" cases.

In other words, can there be a ml.Molecule.from_xyz() and a condition for the .from_file() function to accomodate xyz?

This can be handled already using OpenBabelDriver, but I was definitely hoping to get a from_file() function going that would just use the openbabel backend.

The problem with .xyz files is that the connectivity table has to be guessed, which openbabel can do. But so far I have been trying to avoid it.
