from v1.04 of general:
=====================

In geometry.py,

(*) sphdist() now returns a flattened array as output
(*) Modified docstring in spherematch.py to indicate that the matches for the
first catalog are searched for in the second catalog
(*) Modified docstring in spherematch.py to indicate the order of preference in
implementing keyword inputs nnearest and maxmatches
(*) In altaz2hadec(), added an important change that takes care of the sign
conventions and distinguishes between azimuths that are on opposite sides
(*) In hadec2altaz(), modified to handle any NaN values arising out of machine
precision effects by adding a tolerance factor

In catalog.py,

(*) member function subset() of class Catalog now uses numpy.take() to select
subset from indices instead of using fancy indexing. This will be faster when
size of indices is large.
(*) member function subset() of class Catalog modified to initialize a subset
catalog differently to reflect changes in Catalog attribute structure made in
v1.04.
(*) Modified the docstring of class Catalog to reflect the changes made in its
attribute structure in v1.04 which was forgotten to be made back then.

In my_DSP_modules.py,

(*) Added inverse FFT functionality to FT1D() through use of a boolean 'inverse'
keyword and changed docstring accordingly
