In order to capture short evolutionary phases we assume that over 1 Myr star formation occurs in 10 small episodes every 0.1 Myr, rather than 1 large episode every 1 Myr and nothing in-between.

Add the option to build the database with the high resolution BC03 models rather than the low resolution ones.

Do not store anymore the filter type as all the filters are now assumed to be in units of energy. The conversion from photon to energy is carried out by the import procedure as needed.

Update the nebular models from Akio Inoue. Now log U is sampled in steps of 0.1 dex down to -4. Also deviations from the 10000K case B assumption are taken into account.

Speedup the construction of the database. One of the issues is that models where inserted and committed one by one, which is very slow with SQLite. Now we rather insert all the models at once (for instance all the DL07 models) and commit only when this is done. Even on an SSD, the total run time of python setup.py build goes from 5m20s to 2m42s. The speedup should be even more spectacular on a rotating hard drive.

The pseudo filters used to compute (pseudo) line fluxes must not be
normalised to 1. Also, we set their effective wavelength to the mean
wavelength of the positive part.

Resample the m2005 stellar models at long wavelengths. The reason is that as the sampling is too sparse, the linear interpolation carried out in cigale creates waves that are not only disgracious but that also artificially boost the broadband fluxes flux. Patch based on previous commit that fixed the same issue for the bc03 models.

Update the Dale 2014 model with a finer sampling. We now use the same grid as the Draine models. Courtesy Daniel Dale.

Build the BC03 models only up to 14 Gyr rather than 20 Gyr. The use case for 20 Gyr is very weak. Limiting to 14 Gyr brings two major advantages: it reduces the size of the database from 3.6GB to 2.9GB and it should make the computation faster as the SSP grid size is smaller.

Implement the nebular continuum emission. This has required some refactoring to have some homogeneous naming.

Update with Inoue's latest models computed with a BC03 stellar continuum. 124 lines are now included from the FUV to the FIR.

Remove the author email addresses from the source files and add a AUTHORS.rst
file with the addresses and current affiliation to make it easier to update
the information.

Also, give copyright to the University of Cambridge and the University of
Crete for code developed by authors working there.

Class name should be CamelCased, arguments and variable inside functions
should be lower case.
