"""
Reads a structure from a file. For example, anything ending in
a "cif" is assumed to be a Crystallographic Information Format file.
Supported formats include CIF, POSCAR/CONTCAR, CHGCAR, LOCPOT,
vasprun.xml, CSSR, Netcdf and pymatgen's JSON serialized structures.
Args:
filename (str): The filename to read from.
primitive (bool): Whether to convert to a primitive cell
Only available for cifs. Defaults to False.
sort (bool): Whether to sort sites. Default to False.
merge_tol (float): If this is some positive number, sites that
are within merge_tol from each other will be merged. Usually
0.01 should be enough to deal with common numerical issues.
Returns:
Structure.
