[pstricks] nesc wiring diagram

[Dowding George A]

I am trying to create a wiring diagram figure.  It should look similar
to figure 6 in this paper http://www.tinyos.net/papers/nesc.pdf.

My immediate problem is generating the following type of structure:

________________________________________________
| interface 1 | interface 2 | ... | interface n|        % provides
------------------------------------------------
|              Component Name                  |        % Component
------------------------------------------------
| interface 1 | interface 2 | ... | interface m|        % uses
------------------------------------------------

The should always be a component name. There will be a variable number
of interfaces that each component provides and those that it it
uses. A component need not have both.

Each use interface can be wired to multiple provides interfaces.

Here is the less than satisfactory diagram produced by graphviz of the
complete diagram that I am trying to create. The boxes were easy to
make, but I couldn't get the arrows to look right.
