Detailed Description
Class representing diagnostic computations in PISM.
The main goal of this abstraction is to allow accessing metadata corresponding to a diagnostic quantity before it is computed.
Another goal is to create an interface for computing diagnostics without knowing which PISM module is responsible for the computation.
Technical note: to compute some diagnostic quantities we need access to protected members of classes. C++ forbids obtaining pointers to non-static methods of a class, but it is possible to define a (friend) function
which is the same as creating a method Foo::compute_bar(), but you can get a pointer to it.
Diagnostic creates a common interface for all these compute_bar functions.
