This vector implementation does is optimized for the case of having only a small number of elements, which are stored directly on the vector object rather than being allocated from the heap. If the capacity exceeds this small number, then a heap allocation is done.
This should improve performance in a couple of cases where vectors typically store 1 element and rarely more than that.
In particular, these optimize the traversal of nodes that are not in view, which are discarded more efficiently.
This change affects both the cull and collision traversers.
Gets rid of properties defined as both MAKE_SEQ_PROPERTY/MAKE_MAP_PROPERTY, which are just a bad idea. Instead, adds a way for map properties to define a separate "keys" interface.
