Description
It would be handy sometimes to have a function which says whether an integer is a power of 2; perhaps if its absolute value is a power of 2.
GMP does not have a direct fn for this.

I have implemented in IntOperations both for BigInt and MachineInt.
Also added doc and some tests.
The fn says whether value is positive and is a power of 2.
