Missing methods in LINQ: MaxWithIndex and MinWithIndex

The LINQ library has Max methods and Min methods. However, sometimes we are interested in the index location in the IEnumerable<T> rather than the actual values. Hence the MaxWithIndex and MinWithIndex methods.

These methods return a Tuple. The first item of the Tuple is the maximum or minimum value just the the Max and Min methods. The second item of the Tuple is the index location.

As usually, you might get my LINQ extension from NuGet:

PM>Install-Package SkyLinq.Linq

Usage examples in the unit test.
