Bug#641793: python-mathgl: missing dependency on python-numpy

[Jakub Wilk]

Package: python-mathgl
Version: 1.11.2-2
Severity: serious
Justification: Policy 3.5

In a minimal sid chroot:
| $ python -c 'import mathgl'
| ImportError: numpy.core.multiarray failed to import
| Traceback (most recent call last):
|   File "<string>", line 1, in <module>
|   File "/usr/lib/pymodules/python2.6/mathgl.py", line 26, in <module>
|     _mathgl = swig_import_helper()
|   File "/usr/lib/pymodules/python2.6/mathgl.py", line 22, in swig_import_helper
|     _mod = imp.load_module('_mathgl', fp, pathname, description)
| ImportError: numpy.core.multiarray failed to import

BTW, since your package uses Numpy via a C extension module, you should 
use dh_numpy to generate versioned dependency on it.
