// Name: alu.v
// Module: ALU
// Input: OP1[32] - operand 1
//        OP2[32] - operand 2
//        OPRN[6] - operation code
// Output: OUT[32] - output result for the operation
//
// Notes: 32 bit combinatorial ALU
// 
// Supports the following functions
//	- Integer add (0x1), sub(0x2), mul(0x3)
//	- Integer shift_rigth (0x4), shift_left (0x5)
//	- Bitwise and (0x6), or (0x7), nor (0x8)
//  - set less than (0x9)
