Aestimo does not find the confined energy levels

[MathieuPerrin]

Running aestimo.py on sample_double_qw.py only gives levels in the barrier. I tried decreasing delta_E to check that it was not missing some states due to scanning too fast, or switching to computation_scheme = 0, but it did not work. I have now turned to aestimo_eh.py which does find the states.

Most example files are set to work with aestimo_eh.py,
We will separate both solvers in deferent repositories.

[sblisesivdin]

Instead of separating the aestimo.py and aestimo_eh.py into two repositories, can we simply cancel/erase the aestimo.py and use aestimo_eh.py as the main calculator. We can change it to allow the user to choose calculate electron-only or e-h calculation.

I think this related to issue #22

[h-hebal]

Yes we can, with options on e, h, or e-h.
