New function: bcpowmod()

I'd like to add a new function to the bcmath module. It's very similar to the bcpow() function except that it takes advantage of a fast exponentiation method when used with a modulous. Based on the function call into libbcmath to bc_raisemod() {bcpow() uses bc_raise()}, it would seem to make the most sense to call the php version of the function "bcpowmod()", but with the change in naming conventions I'm more inclined to call it something closer to "bcmath_raisemod()" or "bcmath_powmod()". Am I overcomplicating things by agonizing over the name? I'd love to hear your thoughts.... -Pollita
