 * Choose a field to use as the default color field of a layer.

 * First, exclude fields that are on the exclusion list and don't
 * have names that suggest they contain metrics. Also exclude
 * field names that are blank.
 *
 * Next, look for a field that is of real type and contains one
 * of the preferred names (in order of the preferred names).
 *
 * Next, look for a field that is of integer type and contains
 * one of the preferred names (in order of the preferred names).
 *
 * Next, look for the first field that is of real type (in order
 * of field index).
 *
 * Next, look for the first field that is of integer type (in
 * order of field index).
 *
 * It's possible no field will be chosen (i.e. because all fields
