Probably fixed the build on linux.
Made target test depend on target algorithms.
Added EDLTest to test/main.cpp.
Added EDL::getDirection().
Implemented EDL::routeAnchors().
EDL::routeAnchors() now fills result and frees its variables.
Two fixes in EDL::walkFromAnchor().
Created EDLTest::routeAnchorsTest().
Hope i finally fixed this target dependency...
Fixed types of matrizes for EDLTest.
Fixed gradient magnitude condition in EDL::walkFromAnchor().
Fixed bug causing crash on creating result vector in EDL::routeAnchors().
Clean up result vector in EDLTest::routeAnchorsTest().
Added debug output and fixed subDirection change issue in EDL::walkFromAnchor().
Put algorithm to determine next point into subroutine EDL::findNextPoint().
Enhaned (and fixed) EDLTest::getNextPointTest().
Fixed matrix random access in EDL::findNextPoint().
Some fixes in EDL and EDLTest.

First prototype of EDL::routeAnchors() is ready for review :]

Added parameter angleTolerance for EDL::routeAnchors().
Fixes in EDL::getDirection().

- Now using radian angles.
- Fixed matrix random acces.
