-Operators
-=========
-Operators perform some operation on a given field. In practice an operator can 
-take the form of an explicit matrix (e.g. stored in a Numpy array) or it may be 
-implicitly defined as a function (e.g. an FFT operation would not be encoded in
-a matrix, but performed using an FFT routine). NIFTY includes a framework for 
-handling arbitrary operators, and basic methods for manipulating these 
-operators. Common functions like taking traces and extracting diagonals are 
-provided.
-
-In order to have a blueprint for operators capable of handling fields, any 
-application of operators is split into a general and a concrete part. The 
-general part comprises the correct involvement of normalizations and 
-transformations, necessary for any operator type, while the concrete part is 
-unique for each operator subclass. In analogy to the field class, any operator 
-instance has a set of properties that specify its domain and target as well as 
-some additional flags.
-
-Operator classes
-----------------
-NIFTY provides a base class for defining operators, as well as several pre-implemented operator types that are very often needed for signal inference
-algorithms.
