Where possible, put the #include in the .cc file instead of the header
file.
Include <ostream> when <iostream> is not needed.
Fix a bug in operator<<() for Measurement: NULL value of ap and mobile
was not checked.
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).
/!\ This branch does not compile! (But some single files can.)
/!\ All the following commits are broken code. (Hopefully it will work
/!\ in a few days.)
Backup commit. Beginning of the rewriting work on OWLPS Positioning,
following the new class diagram.
