   We can get this in since basis stuff is done but 2 follow-ups are must
   
   - Remove the limitation that if the column already has inverted/sorted 
index, we will not recommend range index on it. It is perfectly fine to have 
multiple indexes on the same column. We should not make the algorithm 
restrictive by checking for that and instead let the query pattern tell us if 
it is needed. 
   - Test needs to be improved. We need to account for following cases as well
   -- Same column is present multiple times in the same query and different 
queries with =, IN and range predicates. This will anyway be needed when you 
add support for the above
   -- Same column is present multiple times in the same query and different 
queries with RANGE predicates to alter the weight of the predicate
