Main Pal labeling class.
A pal object will contains layers and global information such as which search method will be used.

Select the search method to use.
For interactive mapping using CHAIN is a good idea because it is the fastest. Other methods, ordered by speedness, are POPMUSIC_TABU, POPMUSIC_CHAIN and POPMUSIC_TABU_CHAIN, defined in pal::_searchMethod enumeration
