Mods to fix #93. Eliminated -[NSFNanoEngine NSFP_setFullColumnNamesEnabled]. In all invocations of -[NSFNanoResult valuesForColumn:], all references to columns of the form <tableName>.<columnName> are reduced to just <columnName>. All unit tests pass.
Some code cleanup in -[NSFNanoEngine executeSQL:] around obtaining object values from a query.
