BigInt unsigned integer math library

One of the "missing links" in VB.Net is the absence of the unsigned integer type. This library added that missing functionality and also allows for very large integer types (like an unsigned integer with 256 bits) BigInt is an arbitrary-precision unsigned integer math library. Practically any word size can be used (not just multiples of 8 bits). Math Operators: Add, Subtract, Multiply, Divide, Power, Modulus, and Square Root Equality Operators: IsGreater, IsLess, IsEqual and IsZero Logical Operators: LogicalAnd, LogicalOr, LogicalXor, and LogicalNot Bitwise Operators: ShiftLeft and ShiftRight Assignment Operators: integer, long, double, UInt16, UInt32, UInt64, byte(), string, and BigInt String Output Operators: Hexadecimal, Decimal, Octal, and Binary The comments in the source code constitutes the documentation. A short demo program is also included.
