[Insight-developers] Managing Abort in Filters

[Luis Ibanez]

Bill,

That's a good idea,

I agree with you in that it is a lot of work to add
the try/catch to all the filters. It actually takes
away the simplicity + elegance of some filters...

I'll move the exception to the call of GenerateData
in ProcessObject, and double check the behavior
in the filters that need clean up.

This will be done progressively...
