Unittest for collection classes

Cannot do that due the lack of resources. I am sorry about that.

patch for requested single-threaded unittests for HashSet?

Given how generic those tests are, they might as well be baseline tests for every collection.

Unfortunately, there's no terribly good way to abstract the functionality. I hacked together some string mixin stuff that should work decently like so: version (UnitTest?) mixin GenericCollectionTest?!("HashSet?");

Since the collections themselves are templates, you can't do it the typesafe way (mixin GenericCollectionTest?!(HashSet?)) -- that's not a type.

template to add basic unittests for any collection

How did this work out in the end, dhasenan?

Depending on how general these tests are or not, this ticket may be obsoleted.

would be nice if these worked for the revised containers :)
