class MatrixTransform from Vrml 

	---Purpose: defines a MatrixTransform node of VRML specifying matrix and transform
	--          properties. 
    	--  This  node  defines  3D  transformation  with  a  4  by  4  matrix.
    	--  By  default  :   
    	--  a11=1  a12=0  a13=0  a14=0
    	--  a21=0  a22=1  a23=0  a24=0
    	--  a31=0  a32=0  a33=1  a34=0
    	--  a41=0  a42=0  a43=0  a44=1	
	--  It  is  written  to  the  file  in  row-major  order  as  16  Real numbers 
	--  separated  by  whitespace.  For  example ,  matrix  expressing  a  translation 
	--  of  7.3  units  along  the  X  axis  is  written  as: 
	--  1  0  0  0   0  1  0  0   0  0  1  0   7.3 0  0  1
