Updated SQL Functions

Updated the CalSQLObj and most of the functions in CalSQLAdapter for
naming consistency.  Listed the SQL data overview in SQL
Documentation.txt. Updated the INSERT function. Added 2 GET functions
(single row, and multiple row). Added convert array of CalSQLObj to CSV
(NOT YET TESTED). Updated NthSense code to reflect new SQL db changes
and added better logging.
