Title: allows to set multiple groups of priority regions

This changes allows to set several groups of priority regions by passing two dimensional array without breaking current API. So, for example by passing :priority attribute as a two dimensional array like [ [ 'AU' , 'NZ' ], [ 'US' , 'CA'] ] will generate a two groups of priority countries separated by ---------- . Current API with one dimensional array will work as well.
