Implements a sorted list of type T. The container ensures that all of it's elements are ordered after any insertion. Has some optimization to stop searching after a given value has passed. cmp can set both the direction of the array, and what parameters should be tested. If allowDuplicates set false, the collection will act like a sorted set over an array, and won't allow any insertion of preexisting values. Important: The elements stored within this container must have opCmp override with attributes @safe, nothrow, pure.
