0.7.1
* Changed "flat" to "flatten()" in plot_img.py, as per numpy-1.2.
* Made plot_map.py able to function (only for cyl projection) without basemap.
* Added FITS image I/O convenience functions to img.py.  Defined standard
  FITS format based on VLA images.  

0.7.0
* Moved functions from xrfi.py script into rfi module
* Bugfix in array shape in BeamFlat response() function
* Ported to numpy>=1.2.  Involved:
  - Update flag_by_int in rfi module for new numpy-1.2.ma behavior
  - Update miriad_wrap.cpp, healpix_wrap.cpp, alm_wrap.cpp for new 
    numpy-1.2 API (PyArray_SimpleNew instead of PyArray_FromDims, 
    npy_intp instead of int for array dimensions)

0.6.5
* Bugfix to source strength polynomials as a function of LST
* Changed "-a" in scripting.py so that "-a 0,1,2" includes only baselines that
  involve these antennas without autos (i.e. 0_1,0_2,1_2), rather than all
  baselines that involve any of the antennas.
* Corrected all 3C source postions in src.py using NED.
* Ported to numpy>=1.1, matplotlib>=0.98, basemap>=0.99.  Involved:
    - use of numpy.histogram with new=True in xrfi.py
    - importing Basemap from mpl_toolkits.basemap in plot_map.py
* Split dependency installation into two scripts: install_required.sh
  which installs the minimum needed to be able to install aipy and run
  "import aipy", and install_recommended.sh which installs matplotlib/basemap
  and is needed for most of the scripts that come with AIPY.

0.6.4
* Attempting to support easy_install/setuptools functionality while maintaining
  the simple building that already works.
* Feature added to plot_map.py to give (ra,dec),flux of location on a map
  when right-clicked.
* Changed how plot_map.py plots to use imshow instead of contourf.

0.6.3
* Added _cephes module (from scipy, cutting out fortran dependencies) which
  implements various scientific functions.  Needed j1 = Bessel function.
* Moved source-resolution estimator (using symmetric disc approx) from phs2src
  into separate AntennaArray.resolve_src().  Changed from incorrect sinc
  function to correct j1 (first order Bessel function).
