Detailed Description
       Class defining multi-dimensional subset of an array.

       The slice class represents a multi-dimensional subset of an array,
       specified by three parameter sets: start offset, size array, and stride
       array. The start offset is the index of the first element of the array
       that is part of the subset. The size and stride array describe each
       dimension of the slice. Size is the number of elements in that
       dimension, and stride is the distance in the array between successive
       elements in that dimension. Each dimension's size and stride is taken
       to begin at an array element described by the previous dimension. The
       size array and stride array must be the same size.

       For example, if you have offset==3, stride[0]==11, size[1]==3,
       stride[1]==3, then slice[0,0]==array[3], slice[0,1]==array[6],
       slice[0,2]==array[9], slice[1,0]==array[14], slice[1,1]==array[17],
       slice[1,2]==array[20].
