Convert character to numerical spacing measure for within-array replicate spots.

1	getSpacing(spacing, layout)

`spacing`	character string or integer. Acceptable character strings are `"columns"`, `"rows"`, `"subarrays"` or `"topbottom"`. Integer values are simply passed through.
`layout`	list containing printer layout information

"rows" means that duplicate spots are printed side-by-side by rows. These will be recorded in consecutive rows in the data object.

"columns" means that duplicate spots are printed side-by-sidy by columns. These will be separated in the data object by layout$nspot.r rows.

"subarrays" means that a number of sub-arrays, with identical probes in the same arrangement, are printed on each array. The spacing therefore will be the size of a sub-array.

"topbottom" is the same as "subarrays" when there are two sub-arrays.

Integer giving spacing between replicate spots in the gene list.
