Referring to this and to simplify the access to these nodes I want to 
define a macro that connects two components:

\optBeam{compname1}{compname2}

This is no problem, but I was thinking that it would be nice to allow 
using a node or coordinate pair instead of one compname:

\optBeam{(0,1)}{compname2}
or
\optBeam{compname1}{(4,4)}

would then connect a node with a component. How can I implement such a 
macro. My TeX knowledge is still somewhat limited, so I need some help 
on how to do this best :-)

Thank you,
Christoph
