double import running intrinsic recombination models

[robertdumbrell]

Running this code:

import numpy as np
from  semiconductor.recombination import intrinsic as intr

Aug_C = intr.Auger(material='Si')

print Aug_C.available_models()

I get the error message:

Thanks for the bug!

This is only affecting python 2.7, so not going to jump to the top of my to do list.
This is an example of why the code needs some refactoring; need to remove these cross imports.
