pip version tests fail with buffer wrong dimensions

Hi I am exploring this package, but am unable to run the tests. For example, when I run:

~/scattnlay/tests/python/>>> python test01.py

it prints the error message:

Traceback (most recent call last):
  File "test01.py", line 72, in <module>
    terms, Qext, Qsca, Qabs, Qbk, Qpr, g, Albedo, S1, S2 = scattnlay(x, m)
  File "src/scattnlay.pyx", line 97, in scattnlay.scattnlay (src/scattnlay.cpp:2577)
ValueError: Buffer has wrong number of dimensions (expected 2, got 1)

I get a similar error when trying to run examples/calcspectra.py

Traceback (most recent call last):
  File "calc-spectra.py", line 62, in <module>
    mp=True
  File "../scattnlay/main.py", line 137, in scattnlay

After building from source, I am able to get this working, presumably because the pip wheel is out of date.

There was an API change, however, we tried to make it backward compatible. However, it seems we have missed somthing... Thanks for finding this, next time I have some time for Scattnlay develpment I will try to investigate this.

I had the same issue and identified it as the complex refractive index array being 1-dimensional, i.e. (5, ). I had to numpy.tile() it to (1000, 5) to be compatible with the size array x, which is also (1000, 5).
