MATSim Code

added JavaDoc to loadConfig()

Simplified the code in split() a little bit after the code coverage analysis showed than one if-condition always yielded true (and that could be theoretically be proved as well).

changed some methods in inner classes from public or private to "default" modifier, so access is more restricted from outside but not from inside the class.
moved call to decrementSize() out of an inner class to the main class, similar to the call to increaseSize().

added QuadTreeTest to the test suite.

test cases for QuadTree

several bugfixes to QuadTree:
- member 'size' is no longer declared as transient, because otherwise a de-serialized QuadTree would always have size=0, even if it had objects in the tree.
- member 'values', returned by method values(), is invalidated when objects are added or removed from the QuadTree. before, it could happen that values() did no longer return a true representation of the objets in the QuadTree.
- When calling get(double x, double y, double maxDistance), objects exactly "maxDistance" away from "(x, y)" are now returned as well (according to the javadoc). Before, only objecs with a distance smaller than maxDistance were returned.
Memory improvement:
- QuadTree.Leaf.values (an ArrayList) is now initialized with a capacity of 1, instead of the default capacity of 10. As we rarely have more than one object at one location, most of the entries were empty before, now the list has by default onle one place (which is used in that case).

traveltimecalculator with variable count of time slices to prevent memory waste ... may be this implemntation is a little bit slower then the array based impl ...

fixed javadocs and indentation

src/log4j.xml will be copied to classes/ as well during compilation.

log4j configured by log4j.xml, the default filename had to be changed in Controller's constant attribute.
