[MOAB-dev] iMesh_createEnt vs iMesh_createEntArr

[Tim Tautges]

This will definitely affect the layout of entities in sequences.  If you call the individual entity version, your 
sequences will be laid out in 4k chunks; if the array version, and the arrays are > 4k long, that will be the sequence 
size.  In general, it's usually better to have larger sequences.  But, some of this depends on how much bending over 
backwards is being done, and whether those sequences are ever going to be large.
