/*! \example tests/simplearraytest.cc
 *
 * Tests for aff::SimpleRidigArray and aff::util::Inline.
 *
 * This test program gives an example of the usage of the following classes,
 * functions, and preprocessor macros:
 *   - aff::SimpleRigidArray
 *   - aff::util::Inline
 *   - aff::dump
 *   - #DUMP
 *   - #CODE
