Different databases  support case sensitivity differently.  Sql Server
allows you to configure the database as case insensitive or case
sensitive for identifiers upon creation of the database.  If the
database is configured as case sensitive - then the column "ColOne" and
"colone" are considered different columns.  I think we'll need to
address this as we add support for different database platforms.  Note -
an ODBC Relation could be accessing many different types of databases
which each have handle the case differently.
