    Print a crude ASCII art plot of the SymPy expression 'expr' (which
    should contain a single symbol, e.g. x or something else) over the
    interval [a, b].

    Examples
    ========

    >>> from sympy import Symbol, sin
    >>> from sympy.plotting import textplot
    >>> t = Symbol('t')
    >>> textplot(sin(t)*t, 0, 15)
