[NO-ISSUE][GRAPHIX] Large Graphix update.

Large commit for the following:
- Using AbstractClauseExtension.
- LEFT-MATCH now defaults to a non-foldable-action.
- Refactor of some docstrings to use HTML lists.
- Starting work towards adding using SWITCH and CYCLE at Graphix.
- Adding support for implicit correlated vertex JOINs.
- Adding support for graphs with duplicate schema edge labels.
- Adding support for unconditional schema decoration.
- Adding support for negated edge labels.
- Total revamp for schema resolution: we now take an exhaustive approach.
- Adding support for specifying Graphix compiler options in the config file.
