/*
 * Declaration of class GeneralStorage<N_rank>
 *
 * This class describes a storage format for an N-dimensional array.
 * The dimensions can be stored in an arbitrary order (for example, as
 * a C-style row major array or Fortran-style column major array, or
 * something else entirely).  Each dimension can be stored in either
 * ascending (the most common) or descending order.  Each dimension
 * can have its own base (starting index value: e.g. 0 for C-style arrays, 
 * 1 for Fortran arrays).
 *
 * GeneralArrayStorage<N> defaults to C-style arrays.  To implement
 * other storage formats, subclass and modify the constructor.  The
 * class FortranArray, below, is an example.
 *
 * Objects inheriting from GeneralArrayStorage<N> can be passed as
 * an optional constructor argument to Array objects.
 * e.g. Array<int,3> A(16,16,16, FortranArray<3>());
 * will create a 3-dimensional 16x16x16 Fortran-style array.
