Scupp/BaikalRDWR

[SamuelCupp]

This branch changes the notebook which generates the Baikal and BaikalVacuum to include PreSync features. These include read/write declarations in the schedule.ccl, use of the new function-specific macros, and introduction of a new scheduled function that registers the boundary conditions with PreSync. I have verified that this reproduces the thorns identically with the exception of the aforementioned changes. They also still pass the tests in the ET testsuite, as well as versions of the tests with PreSync active.
