Tauc e1

I just saw that there is a closed form for e1 for the tauc model
See http://scitation.aip.org/content/aip/journal/apl/69/3/10.1063/1.118064

Thanks! I have the code for the real part of the Tauc Lorentz, I guess I have never inserted it just to avoid making things clumsy since we were still trying to get things operative. I will adjust the parameters (I don't remember which conventions I used) and then upload it.

Awesome! IT was too messy and back then avoided to code it since I only needed the imaginary part.

I guess you can put it here following the idea in here of splitting the real and imaginary parts in two private functions.

After an embarrassing amount of time, I pushed the lineshape for the Tauc Lorentz. I still need to test it though. See email for more extensive "Hi" ;)
