Some useful data structures for collections of data

Class Index

Provide indexing for a list. Inner properties can be used for keys, and keys can be tuples of properties.

Class UniqueIndex

Same as Index, but includes checks and optimization to ensure members' keys are unique.

Class Queue

A Queue is a list, with add() and pop(). It ensures members in the queue are not duplicated by not adding the ones already found in the queue.

Class Matrix

A multidimensional grid of values that can be used like a Mapping from a-tuple-of-coordinates to the value at that coordinate. Plus a few other convenience methods.

This is a naive implementation. The hope it is a simple facade to a faster implementation.

Class Relation

Store the many-to-many relations between two domains
