Interface to mark a query result.
There are several implementations of IResult supplied with Memory Analyzer,
together with user interface code to display them.
The org.eclipse.mat.ui.editorPanes extension can be used to extend
the Memory Analyzer user interface to display new custom IResult types.
(Optionally) Return meta data of the result needed to fine-tune the
display of the result.
This could include an additional context, an additional query to run on
selected data from the result , additional calculated columns,
or an indication that the results are already presorted.
