/**
 * The base exception for all comparison failures.

 * which is recognised by IntelliJ so that users can optionally compare the
 * obtained/expected values in a GUI diff explorer.
 *
 * @param message the exception message.
 * @param obtained the obtained value from this comparison.
 * @param expected the expected value from this comparison.
 * @param location the source location where this exception was thrown.
