public interface Densifiable

This interface specifies whether a matrix implementation can be efficiently converted to the standard dense matrix representation. A particular matrix implementation may optimize the conversion by taking advantage of having access to the class' private members. Thus, toDense() is in general more efficient than explicit copy construction.
