ExodusII conversion entries for Tri7, Tet14
ExodusII conversion entries for Tri7, Tet14

I was trying to get SIDE_HIERARCHIC output on these elements, and it
turned out I couldn't get any output on them at all.

This is probably only usable with Exodus 8, but thanks to the
string-based API it'll compile with Exodus 5 too.
