//! Auxiliary class for ParamReader. <br>
//! It stores commands for a ParamReader to manage the current <br>

//! It allows to define the following commands : <br>
//! - read a parameter specified by a precise Number (basic case) <br>
//! - read a parameter then set Current Number to follow its number <br>
//! - read the current parameter (with Current Number) then <br>
//! advance Current Number by one <br>
//! - idem with several : read "nb" parameters from one specified, <br>
//! included, with or without setting Current Number to follow <br>
//! last parameter read <br>
//! - read several parameter from the current one, then advance <br>
//! Current Number to follow the last one read <br>
//! - Read several parameters (as above) but in interlaced lists, <br>
//! i.e. from complex items (each one including successively for <br>
//! instance, an Integer, a Real, an Entity ...) <br>
//! <br>
//! If commands to advance Current Number are not set, it must be <br>
//! set by the user (with method SetCurrent from ParamReader) <br>
//! ParamReader offers methods which create most useful cases <br>
