When trying to install ompy without having numpy or cython, one would currently get an error similar to this:
magneg@fysmac-kef12.uio.no:ompy-master>python setup.py build_ext --inplace
Traceback (most recent call last):
File "setup.py", line 3, in <module>
from Cython.Build import cythonize
ImportError: No module named Cython.Build
This is because setup.py imports numpy or cython in the start. This should be restructured, such that you get a better error message or the dependecies are installed/ or should be mentioned in readme.
