Detailed Description

Fortran Array Boxes (generally called FABs) are objects constructed to interface with arrays in Fortran. Useful operations can be performed upon FABs in C++, and they provide a convenient interface to Fortran when it is necessary to retreat into that language for doing arithmetic operations when performance matters.

FArrayBox is derived from BaseFab<Real>. FArrayBox adds additional useful capabilities which make sense for Real types, such as I/O and L**p norms.

The C pre-processor macro `CH\_SPACEDIM' must be defined to use this class. The internal precision of FArrayBox objects is set by defining either `CH\_USE\_FLOAT' or `CH\_USE\_DOUBLE'

This class does NOT provide a copy constructor or assignment operator.
