laplace by PikoroSoft

LAPLACE:
Run laplace() and enter the function in terms of t in the 
i/o line. It will show you the laplace transformed in terms 
of s.
I tested a couple of times and it worked fine.
Anyways, the most important part of this basic program 
is for all those of you who can't make the user to input
a function and then make the code to use it.
