    Create symbolic variables and inject them into the global namespace.

    NOTE: In SageCloud, you can use var as a line decorator::

        %var x
        %var a,b,theta          # separate with commas
        %var x y z t            # separate with spaces

    Use latex_name to customizing how the variables is typeset:

        var1 = var('var1', latex_name=r'\sigma^2_1')
        show(e^(var1**2))

    Multicolored variables made using the %var line decorator:

        %var(latex_name=r"\color{green}{\theta}") theta
        %var(latex_name=r"\color{red}{S_{u,i}}") sui
        show(expand((sui + x^3 + theta)^2))



    Here is the docstring for var in Sage:

    """
    if 'latex_name' in kwds:
        # wrap with braces -- sage should probably do this, but whatever.
        kwds['latex_name'] = '{%s}'%kwds['latex_name']
    if len(args) > 0:
        return var0(*args, **kwds)
    else:
        def f(s):
            return var0(s, *args, **kwds)
        return f
