Selection syntax:

resname ARG and name CA

Allows use of Julia (possibly user-defined) functions for selection:

atom -> ( atom.resname == "ARG" && atom.x < 10 ) || atom.name == "N"

We do not aim to provide the fastest PDB parsing methods. If speed in reading files, returning subsets of the structures, etc., is critical to you, probably you will do better with some packages of BioJulia, BioStructures in particular.
