Add a common definition file for the Cython modules.
map for testing moved into test/data
Fix typo.
Add -c option to wget, to continue downloads if interrupted and to make sure that running it several times won't download files again
Make testbuild.sh readily functional.
Move file wmap_band_imap_r9_7yr_W_v4_1deg_nside32.fits in test/data, alongside other similar files. The new location is the one expected by test_sphtfunc.py.

Update CHANGELOG.rst
Update INSTALL.rst

users should not directly install the package, see #52,
ReST syntax improvement.
Simplify Alm and Healpix_Map interface.

Add routines ndarray2alm and ndarray2map to view an ndarray as Alm or Healpix_Map. It is not necessary to keep the intermediate arr since it doesn't own its buffer. Neither is keeping an intermediate ndarray, as long as the ndarray, which owns the buffer during the Healpix_Map or Alm lifetime is contiguous and of correct type.
Remove hack.h, not required.
Move Alm and Healpix_Map declaration in _common.pxd.
Use 'C' instead of 'Q' for equatorial coordinates

Aladin does not understand 'Q' for equatorial coordinates; it interprets
'Q' as galactic coordinates. Based on the HEALPix and Healpy source
code, it appears that the Java, C, IDL, and Fortran interfaces support
'C', whereas the C, Fortran, and Python interfaces support 'Q'.

This change affects just the FITS comment and the Python documentation
comments, so it doesn't actually restrict the user from setting
COORDSYS=Q, if necessary.
