/*! \brief Message associated to an Exception.
 * \ingroup CreatingNewAssertions
 *  A message is composed of two items:
 *  - a short description (~20/30 characters)
 *  - a list of detail strings
 *
 *  The short description is used to indicate how the detail strings should be
 *  interpreted. It usually indicates the failure types, such as
 *  "assertion failed", "forced failure", "unexpected exception caught",
 *  "equality assertion failed"... It should not contains new line character (\n).
 *
 *  Detail strings are used to provide more information about the failure. It
 *  can contains the asserted expression, the expected and actual values in an
 *  equality assertion, some addional messages... Detail strings can contains
 *  new line characters (\n).
