An instance of a class with a method __call__ can be called just like
any other function by adding parentheses after the instance
print 'you rang'
# create an instance of callable class JDH
jdh = JDH()
# now call the beast
Since LinearSegmentedColormap defines call, you can do the same
>>> from matplotlib.cm import jet
>>> print jet(.5)
