Potential Edge Cases for Parsing

[lychrel]

1. Some expressions use \equiv instead of =
   • match either when splitting into LHS/RHS
2. Some quantities have multiple associated symbols (e.g. I, I)
   • match either when identifying quantities in other equations
3. Subscripts (e.g. \mathbf{F} vs \mathbf{F}_{mag}
   • Just match the un-subscripted quantity
4. Equation "Output" On Different Sides (LHS and RHS)
   • One vertex is header quantity; other is quantity found on opposite side of parsed equation

Another: false positives when matching input symbols. When matching, remove LaTeX operators like this:

\mathcal needs to be preserved. Otherwise all EMF's will be E's, etc. Don't remove \mathcal when populating symbol dict or when chopping up equations to look for known quantities
