Module grafen::system

Contains the basic structures of an atomic system.

A final system consists of a set of Components. Each Component in turn consists of a collection of Residues, which can be moved around and translated with ease. Each Residue consists of some Atoms. These atoms have positions relative to their parent.

This somewhat convoluted structure is inherited from molecular simulation packages in which atoms are commonly grouped as such. A proper physical way to look at is that atoms can be similarly grouped into molecules.

Structs

Atom	Every atom in a residue has their own code and relative position some base coordinate.
Residue	A base for generating atoms belonging to a residue.
System	Main structure of a constructed system with several components.

Traits

Component

Methods for yielding atoms and output information from constructed objects.
