 - added a new Tcl command: `buffer` which will buffer the geometry of an object or will scale individually each geometry sub element
 - fixed the buffer() method for the Excellon objects (the resulting tool diameters were calculated less than the what was expected)
+- fixed the description for the new Tcl command `buffer`
