If you are doing extended source analysis use this one until v0.2.0 is released.
0.0.5
All dependencies are now explicitly stated in the setup.py file, with the exception of ROOT (we might get rid of this dependency and get MINUIT from somewhere else)
0.0.4
The user can install this version by using pip ("pip install threeML").
The dependencies (numpy, scipy, numexpr, numdifftools...) must be installed separately.
