Assert.Sorted, Assert.Distinct

[GoogleCodeExporter]

Should add two new asserts for testing various conditions:

// Assert that all values in the enumeration appear in increasing
(non-decreasing) order.

Assert.Sorted<T>(IEnumerable<T> values);
Assert.Sorted<T>(IEnumerable<T> values, Comparison<T> comparison);

Optional refinement:

enum SortOrder { Increasing, StrictlyIncreasing, Decreasing,
StrictlyDecreasing }

Assert.Sorted<T>(IEnumerable<T> values, SortOrder sortOrder);
Assert.Sorted<T>(IEnumerable<T> values, SortOrder sortOrder, Comparison<T>
comparison);

// Assert that all values in the enumeration are distinct.

Assert.Distinct<T>(IEnumerable<T> values);
Assert.Distinct<T>(IEnumerable<T> values, EqualityComparison<T>
equivalenceRelation);

Could also support IComparer<T>, etc.

Then we can extend the collection contract verifier to check for
order-based and distinctness invariants.
