 /**
  * Class creating translation matrices from given movements
  *
+ * Three dimensional matrices (3x3) may be used to specify transformation of
+ * points, vectors and complexer structures in a two dimensional cartesian
+ * coordinate system. For more details have a look here:
+ * http://en.wikipedia.org/wiki/Transformation_matrix
+ *
+ * This class implements a convenient interface to create matrixes to move
+ * elements. This matrix may be combined with other transformation matrices, as
+ * usual.
