Changes to the model
- Added a set of Uniprot elements (UniprotRecord class) to Species. Uniprot is mapping between species and structures (species:uniprot == 1:N)
- Added UniprotRecord class which maps uniprot record to a set of PDB records (Structure class)
New annotator which adds PDB annotations
- Creates standard annotations and also adds the mapping to the respective Species objects (Species - 1:N - Uniprot - 1:N - PDB).
