 * gpstk::TypeID - This class was written taking as inspiration ObsID. The
   objective of this class is to create an index able to represent any type 
   of observation, correction, model parameter or other data value of interest 
   for GNSS data processing. This class is extensible in run-time, so the 
   programmer may add indexes on-demand.

    * This class creates an index able to represent any type of observation,

    * data processing.
    *
    * This class is exensible in run-time, so the programmer may add 
    * indexes on-demand. For instance, in order to create a new TypeID object
    * referring INS-related data, and with "ins" as description string,
    * you may write the following:
    *
    * @code
    *    TypeID INS = TypeID::newValueType("ins");
    * @endcode
    *
    * Or using the constructor:
    *
    * @code
    *    TypeID INS(TypeID::newValueType("ins"));
    * @endcode
    *
    * From now on, you'll be able to use INS as TypeID when you need to
    * refer to inertial system data.
