- Adds latex prior table writer (not found to be useful)
- Add special case of 0 to texify_float
- Expose texify_float in core
- Fix confusing argument order in GridSearch

If SFTs where not loaded, i.e. if injectSources was used, no timestamps
are generated. In such a case don't attempt to used them.

- Fixes undefined theta_values -> theta (missed as Ng > 1 isn't tested)
- Import from core rathern than explicitly
- Various PEP8 fixes

If nsegs > 1, a semi-coherent search is performed.

- Adds debug information
- If no data is in a given segment, a nan will be produced. Rather than
  summing this, the code will now replace it with zero and spit out a
  debug message to the effect.

As far as I can tell this should not be here (transient=True) in this
case. Nevertheless, I'm leaving it commented as this is quite a core
routine and I wish to remind myself to investigate it further.

- Adds a simple interface to get grid search given uniform prior
- Fixes detector -> detectors bug (previous versions, the constrains
  where not actually set)
- Adds title functionality to plot2D

- Fixes missing sqrt in the convergence test
- fixes error in periord
- prevents plotting between burn and prod
- allow user to specify upper limit
- refactor code

This was mistakenly added during a testing phase - removed since it is
not used.

- restructures the method into several different functions.
- implements stopping if convergence is met a prespecified number of times
- adds documentation
- will plot the convgerence on the RH axis of the walkers plots

Convergence testing based on the Rubin-Gelman statistic is implemented
via `setup_convergence_test`. This does not truncate the search yet, but
simply adds a trace to the walkers plots for testing

- Addresses incorrecelt named attributes and prevents error if
  sftfilepath is not specified

Also adds thetas_at_ref data to the Writer object

Now forces use of dtglitch = None for no glitches

1) Adds 'add_noise' option (defaults to true)
2) Better checking of Writer for if all glitch parameters have the same
length (avoid strange errors)
3) Fixes issue in which the tqdm ignore command was itself ignored

Transforms the single pyfstat.py into a python module splitting the
relevant code into separate sub-files in pyfstat. This should result in
improved readability.

1) Update README installation instructions
2) Put all set_up code into seperate named functions
3) Remove underhanded mpl backend setter
