Declare data in spatial code example

Example: Declare data in spatial

val data1D        = Array.tabulate(64){i => i * 3} // Create 1D array with 64 elements, each element being index * 3
val data1D_longer = Array.tabulate(1024){i => i} // Create 1D array with 1024 elements
val data2D        = (0::64, 0::64){(i,j) => i*100 + j} // Create 64x64 2D, where each element is row * 100 + col
val data5D        = (0::2, 0::2, 0::2, 0::2, 0::16){(i,j,k,l,m) => random[Int](5)} // Create 5D tensor, the highest dimension tensor currently supported in Spatial, with each element a random Int between 0 and 5
