There isn't a built-in method in Array that does this for you currently. So
you have to roll your own utility function that creates a new Array and
initializes it with the desired row from the source array.
If your 2D array is dense (the Array's Region has the rect property), then
this is fairly straightforward.
If the 2D array is not dense (the Array's Region does not have the rect
property), then this becomes more complex since you will need to decide if
you want the 1D array you construct to be dense, or to match the indexing
structure of the original array. In the later case, you would then need to
use the region algebra functions of Region to build up the 1D region that
corresponds to the points in the row of the 2D region that you want to
select.
