Simple structures and functions to read and write PDB files

Simple data structure:
atoms = readPDB("./structure.pdb")
Array{PDBTools.Atom,1} with 62026 atoms with fields:
index name resname chain resnum residue x y z b occup model segname index_pdb

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.
