for certain lookups.
The rb_tree will act as a general purpose key/value storage, and
also give a performance boost in the cases where the other
simple alternative would be to use a linked_list.
On average this should give on average O(log n) lookups, while the linked_list
would be O(n) at worst.
Caveat, need to run the update script manually after changing the tests (adding or removing tests).
However, modifying existing tests does not require running the update script.
Added a copy of exotic in the repository
exotic automatically generates the skeleton code around the autotests in order to schedule
the tests.
