Python models and classes to supplement the stdlib ‘collections’
Models and classes to supplement the stdlib 'collections' module. Highlights include: * RangeMap: A mapping that accepts a range of values for keys. * Projection: A subset over an existing mapping. * KeyTransformingDict: Generalized mapping with keys transformed by a function. * FoldedCaseKeyedDict: A dict whose string keys are case-insensitive. * BijectiveMap: A map where keys map to values and values back to their keys. * ItemsAsAttributes: A mapping mix-in exposing items as attributes. * IdentityOverrideMap: A map whose keys map by default to themselves unless overridden. * FrozenDict: A hashable, immutable map. * Enumeration: An object whose keys are enumerated. * Everything: A container that contains all things. * Least, Greatest: Objects that are always less than or greater than any other. * pop_all: Return all items from the mutable sequence and remove them from that sequence. * DictStack: A stack of dicts, great for sharing scopes. * WeightedLookup: A specialized RangeMap for selecting an item by weights.
