Syntax
template<typename ElementType>
class TMeshElementArrayBase
Remarks
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.
