DESCRIPTION

This is an improved version of the axis widget. Changes with respect to the previous version are :

the 'pack' has been moved out the widget. One has to do his own packing
it is now possible to work in the coordinates of the axis. The following piece of code draws a line between the points (2 , 3.1) (4 , 4).
```
    $t->create('line',$t->plx(2),$t->ply(3.1),$t->plx(4),$t->ply(4));
    
```
