[MOAB-dev] exceptions & moab

[Tim Tautges]

For the fine-grained data objects (mesh entities, tag values), MOAB uses an array-based storage scheme, rather than a 
C++ object-based scheme.  So, exceptions in constructors aren't as much of an issue as they might be in other C++ mesh 
databases.

ErrorCode has some information, and you can get more information by calling Interface::get_last_error.

All that said, we also recognize the need for better error handling, and there's a task in this year's plan for doing 
that.  Right now, that's as far as the planning has gone, though.
