Glycosylator - v.5.6.3

This is first release of the new Glycosylator using BuildAMol as core library. It comes with several new features and extended functionality.

New Features

• New GlycoShield class and quickshield function to simulate glycan shielding effect on glycosylated scaffold molecules.
• Refactored code contains two new dedicated scaffold classes, Protein and Membrane; the base Scaffold still exists.
• Existing glycans can now be extended or cropped given an IUPAC string input describing the new composition.
• Extended IUPAC string parsing
  - IUPAC string parsing now supports l- and d- isomer specification for individual sugars
  - IUPAC string parsing now supports providing component and linkage IDs to make non-canonical glycans.
• An improved optimizers.make_scaffold_graph function allows users to include bonds within the scaffold molecule, upstream of the root connection, into the optimization to enhance the chances of finding a good conformation for glycans in tricky positions.
  The Scaffold classes now have more versatility in getting data from attached glycan molecules and associated substructures (residues, atoms, etc.).
