Pisano period 
, of an integer n, is the period in which the sequence of Fibonacci numbers modulo n repeats. For example it is not hard to show that 
, 
and 
are 3, 8 and 6, respectively:

This problem is a bit different from the previous Problem 56220. Easy Sequences 75: Easy as Pisano Pi.
In this problem, aside from n, we are given the exponent e and modular base m, and we are asked to calculate:
>> mod(pisanoPi(n^e),m).

Missing from problem description:
1) Forbidden: global, persistent, java, BigInteger .
2) Note that e and m are sometimes missing and sometimes scalar when n is a row vector. When both are missing, behavior should be like Easy Sequences 75. When e is given and m is missing, should be like es75(e^m) were e^m presentable as a double.
When n is a vector and e or m are scalar, use as if e and m were vectors with same size() as n.
