add line width to uml small package

["Pablo Gra\\~na" <pablo grana globant com>]

Hi

I am attaching a patch to make the line width configurable in the uml small 
package. Is this ok? Do you think this is worth commiting in the repo? If that 
is the case, I will continue with the rest of the UML objects.

thanks a lot
