Base class for transfer algorithms that construct transfer Operators between two finite element (FE) spaces.
Generally, the two FE spaces (domain and range) can be defined on different meshes.

Set the desired Operator::Type for the construction of all operators defined by the underlying transfer algorithm.
The default value is Operator::ANY_TYPE which typically corresponds to a matrix-free operator representation. Note that derived classes are not required to support this setting and can ignore it.

Return an Operator that transfers true-dof Vectors from the range FE space back to true-dof Vectors in the domain FE space.
This method is implemented in the base class, based on BackwardOperator(), however, derived classes can overload the construction, if necessary.
