Function for calculating neighbouting polygons.
This function allows the user to calculate, for every given polygon (in the array 'index'), the list of its neighbouring polygons.
- The list of arc definitions, as returned by 'get.arcdata'.
- The list of polygon definitions, as returned by 'get.paldata'.
- An array with the polygons we want to use to calculate their neighbours. It must be an array. If 'index' is not set, then all the polygons are used.
A list in which the first element is a vector of the neighbouring polygons
of the fist element in 'index', and so on.
