An atomic composition calculator for obtaining the stoichiometric information.

For per_system=False calculator has one property count that is 1 for all atoms, and has a sample index that indicates the central atom type.

For per_system=True a sum for each system is performed and the number of atoms per system is saved. The only sample left is names system.

Positions/cell gradients of the composition are zero everywhere. Therefore, the gradient data will only be an empty array.

per_system: boolean:

Sum atom numbers for each system.
