Mixin, allows extension of instance attributes with `AttributeCollection`s

This mixin allows a class' instances' attributes and set of supported
operators to be extended with `AttributeCollection`s.

Note: this class provides a base for using `AttributeCollection`s, it is not
a base class of `AttributeCollection`. This have been a misnomer.

Methods:

    - `_append_attribute_collection`: Append a new `AttributeCollection`
    
Class invariants:

    1. an `AttributeCollectionBase` never contains two identical
    `AttributeCollection`s

_append_attribute_collection(self, collection)

source code


Append a new `AttributeCollection`.

When attributes of collections overlap, the first of overlapping
attributes found in the lookup process is used and the others are
ignored. Lookup happens in the same order as collections were added. (It
is probably best to avoid overlaps.)

Parameters:

    collection :: AttributeCollection
        the collection to add
