Working Fibonacci!
Changed instructions to more formally follow Brainf**k Extended Type 1, including:
@ exits the program or when in a function, ends the function and returns to main program. This replaces !.
$ stores the value of memory into a storage byte.
! retrieves the value from storage and copies to current memory.
Removed & (which used to define the start of a function, now obsolete due to @ effectively marking a function start and end).
Removed % (which used to define the end of a function, now obsolete due to @ marking a function start and end).
Optimizations.
Added optional logging with Loggly.
