This renames the input sftfilepath to sftfilepattern and adds
documentation on how that should be used, i.e. a colon separated list of
wildstring or exact matches. In globbing for all matches, the colon
split is added in. sftfilepath is still used by `Writer` since
an exact path is known.

- In a prior commit, the number of sidebands checked for the normal search
(i.e. SSBprec=2) was erroneously set to M0, rather than 9. This fixes
that.
- Also improves logging output
- Splits of the UniformPriorToGrid run function to produce the data and
  plot separately

- Add peak detection utilities
- Move generate_loudest
- Add SSBprec pass through to MCMC searches
- Fix convergence stat (missing sqrt)
- Minor fixes to plot_walkers (put detection statistic behind walkers)

- Adds injectSources to a variety of other methods
- Adds conversion of injectSource to pfs_input

- Uses the actual prior and not the log-prior as previous
- Adds option to plot the full extent (currently only for uniform
  priors)
- ensures the xlims and ylims are reset correctly

1) Adds check if the truths are not of the correct length (to prevent
corner.corner error)
2) Improve sliding window labels
3) Adds option to plot gps seconds on the sliding window

- 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

No longer saves the emcee sampler itself to the pickle. This was done in
response to a bug encountered by David Keitel in which while dumping the
pickle an error was raised. Fixes #1

Requirement is matplotlib>=1.4 in order to use the style package. Make the
default context ggplot (available in 1.4) and add an error message to
help the user when they have selected one which does not exist.

Adds proper unit support by default, and options ot customise through
the dictionaries

- 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

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

- 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
