This program will try to find the limits of f(x)
as x goes to a, where a can be finite or infinite. Numerical demonstration
in which the program starts one unit away from the the point a
and then chooses another point in between the new point |a-1|
and a. This can be repeated up to 30 iterations. Both right and
left hand limits can be evaluated as well as two sided limits.
