Quadratic equation in FALSE

Example for versions Wouter's FALSE 1.2.CF

This example is identical to the one written for Morphett’s FALSE, except that in Wouter’s FALSE end of input is signaled by end of line character, which is used for breaking the loop. Besides, % in the end of the code deletes the last leftover value from the stack.
