3. Drag a TimeBasedOperator and a TupleBasedOperator. Connect these to the StreamInput
4. Drag a MinusOperator. Connect the TimeBasedOperator and TupleBasedOperator to it
5. Drag a StreamOutput.
6. Build the IEP project, you will see validation errors as copied below:
"ERROR: property "subtractFrom" is required but undefined."

This issue has to do with not configuring minus operator properly.
In minus operator currently user should to select subtract from property and hit ok in the dialog.
This is confusing because when you open the minus dialog and it shows the first operator in subtract from 
field but user has to click ok to be able to save this value in operator property.

This should be fixed such that either when we link we should be able to set this property (subtractFrom)
to the first input operator connected to it, or in the operator dialog by default it should not
show first operator but a text like "select an operator"
