Implement DRACULA using PINT

[paulray]

A great student project would be to implement Paulo Freire's DRACULA code using PINT https://github.com/pfreire163/Dracula

PINT can read in the TOAs one time and compute all the TDB values and solar system quantities once. Then, it can do the adding and subtracting phase wraps and re-fitting quickly, I hope.

Can you suggest a few data sets for which phase connection is non-trivial to try it on? Anything public?

I have at least one really faint Terzan5 MSP that we have not phase connected yet -- some of the TOAs are likely not real (i.e are noise), which makes it even harder. I also have one or two that I think Paulo used Dracula to solve.

In general, a good way to test stuff like this is just to remove data -- use every other day of the NGC6440E data in the PINT, for instance.
