Add index classes to store information about which variable in the vector is which.
Create ElasticTOVBuilder which encapsulates shooting method (still being built).
Modify notes to account for collapse to black hole of core.
Refactor TOVData into gr.hydro package.
Proper refactoring of TOVData.
Improvements to TOVFamily.java for shooting purposes.
Refactor TOVData so that getConservedMass() -> getRestMass().
Shooting to isotropic solution seems to be working. There needs to be the 3-domain solution and black hole solution implemented. The elastic equations integration also needs to be completed.
Updates to evolution. Final integration is unstable at the moment.
