/** \brief Analyze the array shape defined by a Kokkos::View data type.
*
* It is presumed that the data type can be mapped down to a multidimensional
* array of an intrinsic scalar numerical type (double, float, int, ... ).
* The 'value_type' of an array may be an embedded aggregate type such
* as a fixed length array 'Array<T,N>'.
* In this case the 'array_intrinsic_type' represents the
* underlying array of intrinsic scalar numerical type.
*
* The embedded aggregate type must have an AnalyzeShape specialization
* to map it down to a shape and intrinsic scalar numerical type.
