/** This implements the hyperoperation function, which is a generalization of
several mathematical operators:
* n = 0 : the unary successor function (returns b+1; a is ignored)
* n = 1 : addition (a + b) (a+1+1+1+1... b times)
* n = 2 : multiplication (a * b) (a+a+a+a... b times)
* n = 3 : exponentiation (a^b) (a*a*a*a... b times)
* n = 4 : tetration (a^a^a^a ... b times)
* etc
