Support coordinates values and varargs

[Overdrivr]

• Adding a # to a topic will describe specific data types

Examples:
foo#xy (xy coordinates)
foo#xyz (xyz coords)
foo#m22 (2_2 matrix)
foo#m33 (3_3 matrix)

• Associated with varargs interface for publishing
  Publish pair of coordinates x = 0.5 y = 0.9
  TM.publish("foo#xy",0.5,0.9);
  Publish matrix
  0.5 1.0
  1.5 2.0
  TM.publish("foo#m22",0.5,1.0,1.5,2.0);
• And the plots opened by the command line interface will understand all those datatypes.
  Coordinates plotted in a 2D or 3D space
  Matrices will be displayed as transformation matrix on an arbitrary object; in 2D or 3D space.
