Use LaTeX to print 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 print 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 using `print`, 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. Currently, the printing of lists, tuples, and dicts does not work correctly in the qtconsole.
