Hi,
I add some unit test based on the Map class's ones.
Here the changeset :
* add Map<Quaternion> test based on Map from test/map.cpp
* replace implicit constructor AngleAxis(QuaternionBase&) by an explicit
one, it seems ambiguous for the compiler
* replace explicit constructor with conversion type
Quaternion(Quaternion&) with a convert function: conflict between
constructor.
