Changed arrays to vectors because an array doesn't store its size
Fixed complier errors in DBMS.cpp and .h
Created the Comparison class
Changed string name to Table table to be consistent. Especially because
we want the parser to decide whether the relation name actually exists
or not.
Added Dmitry-3 functions
Merge branch 'master' of https://github.com/lincolnharris/csce-315-team-9 into Dmitry
