Merge pull request from asmeurer/sympyprinting...

Merge pull request from asmeurer/sympyprinting Use LaTeX to display, on output, various built-in types with the SymPy printing extension. SymPy's latex() function supports printing lists, tuples, and dicts using latex notation (it uses bmatrix, pmatrix, and Bmatrix, respectively). This provides a more unified experience with SymPy functions that return these types (such as solve()). Also display ints, longs, and floats using LaTeX, to get a more unified printing experience (so that, e.g., x/x will print the same as just 1). The string form can always be obtained by manually calling the actual print function, or 2d unicode printing using pprint(). SymPy's latex() function doesn't treat set() or frosenset() correctly presently (see http://code.google.com/p/sympy/issues /detail?id=3062), so for the present, we leave those alone.

      Usage:

        ipython-get-history.py sessionnumber [outputfile]

      If outputfile is not given, the relevant history is written to stdout. If

      outputfile has a .py extension, the translated history (without IPython's

      special syntax) will be extracted.

      Example:

        ./ipython-get-history.py 57 record.ipy
