#4202: latex derivatives of symbolic functions nicely

This patch makes it so that symbolic functions attempt to call maxima to
get a latex representation before printing out the default
functionname(arguments) notation.
Here is some Sage code that did derivative printing. I post it here since
this code tries to intelligently print partials versus total derivatives,
while maxima's seems to only print total derivative "d"s. If there is
interest, we can include this as part of the _latex_ function.
{{{
if self._f._name == 'diff':
if len(self._args[0].variables())==1:
d_latex = "d"
else:
d_latex = "\\partial"
variables = [(self._args[2*i+1]._latex_(), self._args[2*i+2])
for i in xrange((len(self._args)-1)/2)]
variables_latex = ''.join([d_latex+var if power==1 else
d_latex+var+"^%r"%power
for var,power in variables])
order = sum([power for var,power in variables])
if order == 1:
order_latex = ""
else:
order_latex = "^%r"%order
return "\\frac{%s%s}{%s}(%s)"%(d_latex,
order_latex,
variables_latex,
self._args[0]._latex_())
}}}
