Of11 amr path logic (#22)

* Add none as default or optional refinement controller

* modified initial mesh and calrified README.md

* cleaned README.md

* reorganized additivefoam solver and libraries

* Refactored solver to build from additivefoam-dedicated libraries. Improved stability of thermodynamic solution by removing explicit correction outside of solidification range (this prevents the need for persistence in AMR coarsening). Currently, the gradient based-amr is a WIP along with moving foamToExaCA to a FunctionObject that supports AMR

* removed old foamToExaCA which does not support AMR. The new ExaCA FunctionObject in a work-in-progress and currently interpolate from cell-centers to cell-vertices at every execute() call of FunctionObjects

* cleaned up uniformInvervals logic based on existing scan path functionality

* added in optional user-defined bounding box to increase refined mesh span around the moving beam

* changes to refinement controller update return logic

* updated AMR to set uniform intervals based on scan path logic start and end times. AMR continues to be called at these intervals for the remainder of the simulation to capture solidifying cells. latent heat logic corrected to remove explicit correction that causes numerical instabilities

* simplified refinement controller logic. The refinementField is only updated on intervals, so there is no need for condition calls to mesh.update()

* cleaned up refinementController and updated comments
