If the given tstart is before the minStartTime this will error - so
instead, select the minStartTime

Previously, if the data span was shorter than the requested tstart-tend,
the code would choke when attempting to calculate twoF over a range
without any data. Instead, the code now automatically only compute twoF
over a range with data in it.

1) Add ability to in F0s, F1s etc in grid search directly (use tuple as (is)
2) Update cumulative legend
3) Add option to produce pfs_input directly to calculate_pfs
4) Fix spelling mistake
5) Update transient example in the paper

- Adds option to underplot the preducted Fstat 1-sigma variation in
  twoF_cumulative plots
- Adds isolated function to predict Fstat (wrapper to lalapps function)
- Adds detector colours dictionary: use elsewhere

- Expose generate_loudest
- add check if par exists
- All read_par to read_loudest
- Make the default save_fig to be True in plot_corner

Makes this an optional module, adds it to the requirements and README.md

A hack fix for the internal error in LALSUITE - this should be reversed
once we have solved the fundamental issue: if the data contains no sfts
for that period, return 0 not nan

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.

- 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

- 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.
