Detailed Description

Specialization of Attribute for booleans.

Attribute needs a specialization for bool, since vector<bool> uses compressed storage (1 bit per boolean), that is not compatible with the attribute management mechanism. This wrapper class uses an Attribute<Numeric::uint8> and does the appropriate conversions, using an accessor class.
