=head1 DESCRIPTION

Infix2Postfix as the name suggests converts from infix to postfix
notation. The reason why someone would like to do this is that postfix
notation is generally much easier to do in computers. For example take
an expression like: a+b+c*d. For us humans it's pretty easy to do that
calculation.  But it's actually much better for computers to get a
string of operations such as: a b + c d * +, where the variable names
mean put variable on stack.
