A base-class for coder-friendly and TAL-friendly element
collections.
Subclasses must override either __iter__ or both __len__ and
__getitem__.
In most cases, it is a good idea to override __contains__, and __len__
(even if the subclass is overriding __iter__).
The class attribute _allow_filtering can also be overridden to
disallow the use of the filter method.
