> Hive's current behavior on Quoted Identifiers is different from the normal interpretation.
Quoted Identifier (using backticks) has a special interpretation for Select expressions(as
Regular Expressions). Have documented current behavior and proposed a solution in attached
doc.
> Summary of solution is:
> - Introduce 'standard' quoted identifiers for columns only. 
> - At the langauage level this is turned on by a flag.
> - At the metadata level we relax the constraint on column names.
