//! This class is intended to record data attached to a case to be
//! exploited.
//! Cases can be :
//! * internal, i.e. for immediate debug
//! for instance, on an abnormal exception, fill a CaseData
//! in a DB (see class DB) then look at its content by XSDRAW
//! * to record abnormal situation, which cause a warning or fail
//! message, for instance during a transfer
//! This will allow, firstly to build a more comprehensive
//! message (with associated data), secondly to help seeing
//! "what happened"
//! * to record data in order to fix a problem
//! If a CASE is well defined and its fix is well known too,
//! recording a CaseData which identifies the CASE will allow
//! to furstherly call the appropriate fix routine
//!
//! A CaseData is defined by
//! * an optional CASE identifier
//! If it is defined, this will allow systematic exploitation
//! such as calling a fix routine
//! * an optional Check Status, Warning or Fail, else it is Info
//! * a NAME : it just allows to identify where this CaseData was
//! created (help to debug)
//! * a LIST OF DATA
//!
//! Each Data has a type (integer, real etc...) and can have a name
//! Hence, each data may be identified by :
//! * its absolute rank (from 1 to NbData)
//! * its name if it has one (exact matching)
//! * else, an interpreted identifier, which gives the type and
//! the rank in the type (for instance, first integer; etc)
//! (See NameRank)
