[udf-dlm-develop] Matrix support!

[Eduardo S. <es...@la...>]

Folks,

I've checked in new udf.c and udf.h files.  These now support
reading matrix sensors.  I have tested with ImFhWIC, and I seem
to get back something reasonable.  

Code is available on the CVS repository only.  I will not make
an official release yet.  

Now I know some of you don't know CVS, and may not feel like investing 
the time to learn it.  The only thing I can say to that, is to give
you my word that it is worth your while.  Once you've spent some time
with CVS, you will understand my point of view.

Instructions for accessing the UDF-DLM repository are at:

    http://sourceforge.net/cvs/?group_id=868

Note that there's a link at bottom, "Browse CVS Repository", which
provides full Web access to everything.

Some helpful links to CVS documentation and introductions may be found at:

    http://sfdocs.sourceforge.net/sfdocs/
    http://cvsbook.red-bean.com/

(the latter is an online copy of the "CVS book", a fairly decent 
reference for newbies and experts alike).

-----------------------

Some important caveats about the checked-in source code:

    * these changes do not apply to /GROUP and /COLLAPSE !  That
      is left as an exercise for the reader.

    * regular (non-matrix) sensors _may_ be broken!  I haven't 
      even had time to run tests... the purpose of this checkin
      is to provide the preliminary hooks, and a baseline for
      further editing.  

Enjoy,
^E
