   *  @brief  Class defining one-dimensional subset of an array.
   *
   *  The slice class represents a one-dimensional subset of an array,
   *  specified by three parameters: start offset, size, and stride.  The
   *  start offset is the index of the first element of the array that is part
   *  of the subset.  The size is the total number of elements in the subset.
   *  Stride is the distance between each successive array element to include
   *  in the subset.
   *
   *  For example, with an array of size 10, and a slice with offset 1, size 3
   *  and stride 2, the subset consists of array elements 1, 3, and 5.

   *  A slice_array is a reference to the actual elements of an array

   *  operator[](slice) on a valarray.  The returned slice_array then permits
   *  carrying operations out on the referenced subset of elements in the
   *  original valarray.  For example, operator+=(valarray) will add values
