[Positioning] Work on AccessPoint and Measurement Modification of AccessPoint and Measurement to fit the class diagram. Adding class PosUtil, for static utilitary functions (will be the successor of the false library libowlps-positioning).

[Positioning] Some ReferencePoint code -> PosUtil ReferencePoint::complete_with_dummy_measurements( map<string, Measurement>, map<string, Measurement>) becomes PosUtil::complete_with_dummy_measurements( unordered_map<string, Measurement>, unordered_map<string, Measurement>) ReferencePoint::compute_ss_square_distance( map<string, Measurement>, map<string, Measurement>) becomes PosUtil::ss_square_distance( unordered_map<string, Measurement>, unordered_map<string, Measurement>) map<string, Measurement> ReferencePoint::get_all_measurements_sorted() is now private, returns an unordered_map instead of a map, and is renamed ReferencePoint::get_all_measurements(). Note that we now use unordered_maps for these functions. The use of sorted lists (maps) was useless, as stated in the commit message of e9eab687 (Wed Jun 2 12:37:43 2010 +0200).

[Positioning] Doxygen comments + fixes - Add/update comments to be Doxygen compliant. Translate existing comments in English. - Various fixes (more or less importants): - NULL pointer verification when adding an element to a vector of pointers. - Add some missing accessors. - Add some more error handling with exceptions. Class Stock: correct accessors (pure read accessors do not create a missing element any more, but throw an exception). - Makefile: Add 'doc' target. - Update TODO (some things noticed when reviewing the code for comments).
