Review: MoreEnumerable.Incremental()

[GoogleCodeExporter]

Purpose of code changes on this branch:

Rev 137: Implementation of the Incremental operator which visits each
adjacent pair of elements in a sequence: {N,N+1}, {N+1,N+2}, {N+2,N+3} ...
and applies a projection to them. An overload is available that is also
supplied the zero-based index of the *second* element in the pair. The
number of items in the result sequence will always be one less than in the
source. Incremental returns an empty sequence if passed a sequence of less
than two items. Incremental operates in a deferred, streaming fashion. 

When reviewing my code changes, please focus on:

* The public interface of the extension method.
* The effectiveness and clarity of the available XML comment documentation.
* How well this operator fits into the MoreLINQ ecosystem of
extension methods.
* The extent of coverage available from the corresponding unit tests.
* Whether edge cases are correctly identified and handled in the
implementation and tests.

After the review, I'll merge this branch into:
/trunk

Seems redundant with Pairwise.

Following no response from ambientlion (who possibly/assuming lost interest 
given it has taken years to get this far), taking ownership of issue to 
consider as addition for MoreLINQ 2.0 milestone.
