Does phase change during runtime?

[cpaniaguam]

The behavior of odeChamber and affect! (also build_matrix) depend on phase.

If phase does not change in runtime, checking its value is unnecessary. It seems like phase can be mutated by the IC_Finder_Functions in affect!

Consider creating a type for phase to create specialized versions of these functions in the same fashion as with the composition types.
