**
**  This class contains the information that is shared between all
**  units of the same type and determins if a unit is a building,
**  a person, ...
**
**  The unit-type class members:
**
**  CUnitType::Ident
**
**    Unique identifier of the unit-type, used to reference it in
**    config files and during startup. As convention they start with
**    "unit-" fe. "unit-farm".
**  @note Don't use this member in game, use instead the pointer
**  to this structure. See UnitTypeByIdent().
**
**  CUnitType::Name
**
**    Pretty name shown by the engine. The name should be shorter
**    than 17 characters and no word can be longer than 8 characters.
