/* This header declares a macro, ASSERT(Expression). ASSERT evaluates the input expression and verifies that
 * it is true. If the expression is false, an error message will be printed to the log with info on what went
 * wrong and (in debug builds) trigger a debug break. Application execution is aborted. In public release builds,
 * asserts are compiled out entirely, so neither log messages nor debug breaks will occur.
 *
 * Alternatively, this file also declares an ENSURE macro, which is guaranteed always executes and will never be
 * compiled out, regardless of build configuration.
