The MultiFab class is publically derived from the
FabArray<Real,FArrayBox> class. It is a collection (stored as an array) of
FArrayBoxes useful for storing floating point data on a domain defined by
a union of rectangular regions embedded in a uniform index space. The
MultiFab class extends the function of the underlying FabArray class just
as the FArrayBox class extends the funtion of BaseFab<Real>. Additional
member functions are defined for I/O and simple arithmetic operations on
these aggregate objects.
This class does NOT provide a copy constructor or assignment operator.
