Interfaces and classes for protein structure (PDB).

## Parse PDB files

To load a PDB file see the PDBFileReader class in the IO subpackage.

## Parse mmCif files

To laod a mmCif file see the MMCIFFileReader class.

## The Structure object

The Structure object allows to access the PDB header information as well as to the data from the ATOM records. The header information is currently available through the following objects:

- PDBHeader
- DBRef
- Compound

The structure object provides access to the data from the ATOM records through a hierarchy of sub-object:

      Structure
              |
              Chain
                  |
                  Group
                      |
                      Atom
