Functional deadfish

Functional Deadfish is an expansion of Deadfish which adds "functions"

Its syntax is the same except for the f and c command. All commands between two f commands become part of the function. Functions do not have arguments. The function's name is the number that the iterator is at. The function can be called by using the c command when the iterator is at the functions name.

example: fiofifdofdcccicc prints 12321
