Detailed Description
abstract base class for time-dependent data at a level of refinement.
This is an abstract base class for data at the same level of refinement within a hierarchy of levels. The concrete class derived from AMRLevel is called a {physics class}. The domain of a level is a disjoint union of rectangles in a logically rectangular index space. Data is defined within this domain. There is also a problem domain, which may be larger, within which data can, in theory, be interpolated from some coarser level.
{\tt AMRLevel} is intimately entangled with the class {\tt AMR}. The {\tt AMR} contains a collection of {\tt AMRLevel}s which represent a hierarchy of levels of refinement. The class {\tt AMR} is responsible for calling the correct member functions of {\tt AMRLevel}. The user is responsible for implementing the physics class, and might never call any {\tt AMRLevel} functions described here.
