+== whats this ==
+!QuickAnimation is a wrapped lookup-table, that returns Values from Positions between 0.0 and 1.0
+
+The Joke is, that one can add Key-Frames (with any values, and position between 0.0 and 1.0) and then retrieve a Value between those !KeyFrames.
+
+Acctually it is like a curve from 0.0 to 1.0.
+
+
+== usage ==
+{{{
+#!cpp
+  QuickAnimation test;
+
+  test.addKey(.5, 10.0);
+  test.addKey(.6, 3);
+  test.addKey(.6, 3);
+  test.changeValue(.6, 4);
+  test.addKey(.0, 1);
+
+  test.debug();
+
+  for (float f = 0.0; f < 1.0; f+= .1)
+    printf("%f  -  %f\n", f, test.getValue(f));
+}}}
+outputs:
