Arun vs. BeagleClient -- round 1

["Arun Raghavan" <arunissatan gmail com>]

Hello All,
I've run into a bit of a hitch while trying to write some code that
uses the BeagleClient API to connect to beagled and do some searching.

I've attached the code for a Search class. I instantiate an object
with the query "xesam". I see the search happening on the beagled
side, but the HitsAdded event does not occur. The Main() method runs
an infinite loop iterating on DBus messages waiting for this.

Anybody got any clues on why I'm not getting callbacks on OnHitAdded?
I can post all the code if required, but it's a little messy right
now.

TIA!
