Detailed Description

template<typename ElementType>
class TMeshElementArrayBase< ElementType >

This defines the container used to hold mesh elements. Its important properties are that it acts as an associative container (i.e. an element can be obtained from a given index), and that insert/delete/find are cheap. The current implementation is as a TSparseArray, but we abstract it so that this can be changed later if required, e.g. a TMap might be desirable if we wished to maintain unique indices for the lifetime of the container.

Custom serialization for TMeshElementArrayBase. The default TSparseArray serialization also compacts all the elements, removing the gaps and changing the indices. The indices are significant in editable meshes, hence this is a custom serializer which preserves them.
