""" NIFTy class for endomorphic operators.
The NIFTy EndomorphicOperator class is a class derived from the
LinearOperator. By definition, domain and target are the same in
EndomorphicOperator.
Attributes
----------
domain : DomainTuple
The domain on which the Operator's input Field lives.
target : DomainTuple
The domain in which the outcome of the operator lives. As the Operator
is endomorphic this is the same as its domain.
