new implementation: parametrized by a quantity type QT and the storage type ST (default: double); it is assumed that QuantityTraits<QT> provides the following interface: Dimension - the dimension object of the quantity UnitType - the base type of all units associated with the quantity UnitList - the list of all units associated with the quantity in the form of a Loki::Typelist; all units in this list must be subclassed from UnitType DefaultUnit - the default unit, must be a member of UnitList

print a quantity
outputs the object it is called on through the output stream os; needs not be called from used code, rather, a call to operator<< is more often used; the output depends on the status stored in the PrintStatus singleton: the name and the symbol of the quantity are only printed if the corresponding status flags in PrintStatus are set to true; if the corresponding flag is set to false, the default empty string is used; if either the name of the symbol is to be printed, an equal sign is added to the output stream, otherwise, the equal string is also left empty; the name, symbol and equal sign are placed on the ostream in this order, before the pure virtual member function print_value is called, which does the same for the value and unit of the quantity.
