This a major uplift with drastic changes to the Atmophere class that
will hopefully simplify the way files are read and handled.
Checking out on the major commit with modifications to the Atmosphere
grid class.
Fixed some minor problems with the renaming of the Atmo_phot_BTSettl7
class and the __init__.py of the Atmophere sub-module. Also added a
pdf for the plot made in Example1 so that one can compare the results.

Note that this version should be overwritten by the dev branch. This
commit was just a temporary fix in order to have a working version of
Icarus.
Commit to switch to master's.
Finished including and testing Doppler boosting.
Removed files located in Examples/Tests from tracking.
Added Example 3 to demonstrate the use of the new Doppler boosting
functionalities. Also sub-classing of Photometry into
Photometry_doppler in order to handle Doppler boosting at the high
user level.
