Detailed Description

Template for classes storing finite set of named values.

The primary purpose of this class is initialization of enum variables. Since C++ provides no reflection, in particular no access to enum identifiers as strings, you has to construct the Selection object consistent with an enum you want to initialize.

Similarly to Type::Record and Type::Abstract the Selection class is only proxy to the actual data.

Usage:

enum Colors { blue, white };
const Selection & SomeClass::get_selection_input_type() {
 return Selection("Colors", "Set of color.")
     .add_value(blue, "blue")
     .add_value(white,"white","White color") // with optional item description
     .close();
}

TODO: We can not guarantee full compatibility of the Selection with corresponding Enum type the Selection can have fewer values since we can not get number of values in the Enum. Therefore we either have to move under C++11, where enum classes may provide elementary reflection or have Selection of simple ints.
