Updated default layout

• Switched default layout (can be overridden with --layout flag) to force-directed
  since force-directed-cl may not work on all machines.

Removing duplicate family member nodes

• Fixed duplicate node issue by removing nodes and edges from a network if a family node, contains
  the node in its memberlist. Any edges are shifted to the family node with duplicates
  merged where possible.

Cytoscape Layouts

• New default behavior: force-directed-cl layout is now applied on
  networks via py4cytoscape library and a running instance of Cytoscape.
  Alternate Cytoscape layouts and the networkx "spring" layout can be
  run by setting appropriate value via the new --layout flag

Update style.cx

• Updated data/style.cx by renaming Protein to protein and SmallMolecule
  to smallmolecule to match the new normalization conventions
