For redshift and analysis module, we don't need to evaluate each
parameter as an array as we don't expect arrays here (and that force us
to use parameter[0] to get the value).

Configobj return strings, to evaluate the booleans on their "string"
content.

Instead of prefixing the key in the SED with the module name, we postfix
them with the same postfix as the module name if any. This makes easier
to inter-change modules adding the same information (for instance
attenuation modules adding the attenuation value).
That implies that when using several modules adding the same
information, one must postfix the name of each.

That implies that when using several modules adding the same

When one value for a parameter is a list (for instance the list of
attenuation keys for re-emission modules) we had to use the "eval [["a",
"b"]]" notation. Convert these module to use a single string with items
separated by a & ("a & b").

WARNING we must still change the way parameters are evaluated not to
return everytime a list.

So that the configuration files and the serialized data have a logical
order.

Use sphinx with astropy _templates (it would be great to make pcigale an
affilated package).
Make the skeleton of the documentation.
Start to write pcigale script usage.

We follow the astropy version number scheme VERSION-RELEASE.

Take the Maraston 2005 models from the right page (see Readme.rst). The
one we were using come from an old (but still alive) page and the Kroupa
half solar metallicity SSP had a problem that was corrected around 2011.

Also, we keep all the unused SSP in the "not_in_base" folder.

In Maraston 2005 module, use Z value for metallicity (instead of
log10[Z/H]) and homogenise IMF name with BC03 ones.

PEP8-fication of the code and correction of various typos and spelling
mistakes.

If the SED is redshifted, apply the redshift before checking the
boundaries.

Prepare to make it possible to get the flux in a filter without taking
into account the contribution from the spectral lines.

Store the spectral lines in the SED as a three axis numpy array and add
a method to add new sets of lines.

Add the necessary structures and methods to add and retrieve them from the
database.
