Set Center Span: various issues

[GoogleCodeExporter]

  * Change default to dwell to be 1 ms instead of 2 ms.
  * Toggle between center/span and start/stop (deactivate them in turn), so
it’s clear which are the parameters being sent to the mwave generator.
  * Check: does it do a “read” when we first start or a “read to control”?
We probably want just a “read”.

Regarding the second item, "* Toggle between center/span and start/stop 
(deactivate
them in turn), so it’s clear which are the parameters being sent to the mwave 
generator"

-->  actually, the way it works (with screen updating whenever a field is 
changed)
would probably be just fine, if it were calculating things correctly. However, 
when a
center/span is specified, the start & end points get calculated incorrectly. 
Probably
just a minor error, like the center value being hooked up someplace instead of 
the
span value.

It might still be good to have a default dwell time be 1ms, but most of this is 
implemented now.  Closing.
