+//! The TrackManager handles the flow of the Players through the game.
+/**
+   \todo write the methodes
+
+   <b>The TrackManager works as followed:</b> \n
+     \n
+   <b>1. Initialize it, by setting up the Graph. You can do this by using the following Commands.</b>
+    \li workOn(): changes the ID that will be altered through the changes.
+    \li setType: lets you set the CurveType of the Curve we are Working on. (default is BezierCurve, set this as early as possible, for this uses resources).
+    \li setLength(): sets the length of the current path in seconds.
+    \li addPoint(): adds a point to the Curve.
+    \li addHotPoint(): adds save/splitpoint.\n
+    \li fork(): adds some interessting non-linear movments through the level (fork will force addHotPoint if not done then).
+    \li condition(): decides under what condition a certain Path will be chosen.
+    \li join(): joins some tracks together again. Join will set the localTime to the longest time a Path has to get to this Point)
+    \li setSavePoint(): Sets a HotPoint into a savePoint. A Savepoint can be used as a rollbackpoint if a Player gets shot.
+
+
+    look out: <b>SAVEPOINTS CAN NOT BE FORKS</b> (but joins), because the condition is really hard to guess if you do not give some impuls. \n
+\n
+   <b> 2. Runtime knows the following: </b>
+    \li calcPos(): returns the current position on the track
+    \li calcDir(): returns the current Direction the track is flying on.
+    \li tick(): makes a Step on the Path. increases localTime by dt.
+    \li choosePath(): a Function that decides which Path we should follow.
+   
+   TrackManager can be handled as a StateMachine.
