Release 0.5.2

Full restraints support in both receptor and ligand has been implemented

• Restraints are specified as residues using the original numeration from the PDB input structures.
• Total number of swarms is filtered on the distance to residues in the receptor surface.
• During the simulation, the energy is biased depending on the percentage of restraints satisfied.
• The script lgd_filter_restraints.py is intended for filtering out structures predicted which don't satisfy the input restraints.
