// Assertion tool for Devel builds, intended for sanity checking and/or bounds checking
// variables in areas which are not performance critical.
//
// How it works: This function throws an exception of type Exception::AssertionFailure if
// the assertion conditional is false.  Typically for the end-user, this exception is handled
// by the general handler, which (should eventually) create some state dumps and other
// information for troubleshooting purposes.
//
// From a debugging environment, you can trap your DevAssert by either breakpointing the
// exception throw below, or by adding either Exception::AssertionFailure or
// Exception::LogicError to your First-Chance Exception catch list (Visual Studio, under
// the Debug->Exceptions menu/dialog).
