getGenres

GenreService.getGenres(int letterIndex,
                      int startItem, 
                      int maxItems)

Get a list of genres. The letter index is the index in the alphabetical register (i.e. "0-9", "A-C", "D-F", etc.) where index 0 is "0-9", index 1 is "A-C", etc. and -1 means all. The startItem is the first item from the list to return, i.e. if the result has 100 items and you set startItem to 50, you will get items 51 - 99 (items start with index 0) in the result. The maxItems parameters specifies the maximum number of items to return where 0 or a negative value means all items. Use the last two values for implementing pagers. The return value is a list of genres.
