PS7, Line 22: /**
            :  * Interface for the analyze method which returns an 
AnalysisResult.
            :  */
> The docs can be more detailed.
So my default thinking all along (as shown with my first commit) is to leave 
the legacy code alone as much as possible.

But...

Maybe I thought of a way to handle the Exception external to AnalysisResult, 
but before I implement, lemme run it past you...

The whole reason we need AnalysisResult object is that we need the Planner to 
have the result of the analysis.  And the planner needs the mutated Analyzer 
and StatementBase objects.

The legacy code also requires the AnalysisResult to be instantiated within this 
method. But here's the thing...

Internal to this method, we also have access to the AnalysisDriver.  This 
object also has the most recent mutated Analyzer and StatementBase.

So if I replace all analysisResult_.getStmt() and analysisResult_.getAnalyzer() 
calls with analysisDriver_ WITHIN this method, we wouldn't need the 
AnalysisResult object in the exception case.

I would have to re-insert the getStmt() and getAnalyzer() methods on the 
AnalysisDriver interface to do this.

Did that make sense?  If so, I'll code an alternative version that would prolly 
be more inline to what you're suggesting and prolly a better design.
