This file provides macros and functions for compile-time and run-time assertions.

When the OI_DEBUG preprocessor value is defined, the macro OI_ASSERT is compiled into

the program, providing for a runtime assertion failure check.

C_ASSERT is a macro that can be used to perform compile time checks.
