* default MatrixBase ctor: make it protected, make it a static assert, only do the check when debugging eigen to avoid slowing down compilation for everybody (this check is paranoiac, it's very seldom useful)

Browse Source 
* add private MatrixBase ctors to catch cases when the user tries to construct MatrixBase objects directly
