rectangle-selectable plot (experimental)
New functionality in restrict command: choose by date
Add format option to read command.

We can now read more than three columns! The supported formats are
the ones listed at
http://obswww.unige.ch/~segransa/yorbit/fileformat.html
namely CORALIE, DRS3.4, DRS3.5 and a basic one with just 3 columns.
The default format is DRS3.5
This needs documentation, urgently!
km/s in plots
configuration of plots is done (only) in matplotlibrc file
Rename and take care of extra quantities. New plot command options.

Quantities like fwhm, bisector, etc, are now stored in a namedtuple
belonging to the system. This introduces a known dependency on
Python >= 2.6 but facilitates accessing the variables.
The plot command now has options to do (simple) plots of these
quantities.
Add correlate command: do plot and show correlation coefficients.
add Fortran code for gls periodogram; needs testing
Add 1st macro script; ability to run macros is here already.

The 'run' command from IPython already has the ability to work like
a macro reader/executer, with only simple changes to the script
files to allow for the OPEN magics. Don't forget the -i option to
expose the current namespace.
add DawsonFabrycky files and compilation rules
Still working on MultiNest integration
Add dawfab command to run the Dawson-Fabrycky algorithm.

This procedure tries to distinguish between real frequencies in the
data and aliases introduced by the uneven sampling. The current
implementation is based on Annelies Mortier's code with minor
modifications for integration in OPEN. The performance is poor as of
right now.
cleanup dawson fabrycky
fix issue in restrict help: I think it covers everything now
Reimplement genetic algorithm.

Decided to switch from galileo.py to the DEAP implementation of a
simple genetic algorithm. This is a more mature library with plenty
of interesting stuff under the hood. Note: this obviously introduces
a dependency on DEAP, but I think is is quite easy to get/install.
There is still a bug as it sometimes halts for no apparent reason.
Deleted galileo.py from repo
Update ignore rules
Conversion between julian day and date
new options for restrict command
working on multinest analysis
