Skeleton for smart sql helper
Updated project file and slightly more code (and tests)
Full smart sql -> sql algorithm ported to objective-c (along with tests) - NB: all lookups are done directly in the database, there is no caching unlike the java implementation
Adding helper method convertSmartSql to SFSmartStore
Hybrid project changes
Exact/like/range queries are translated to smart queries - smart store only runs smart queries
SFSoupCursor renamed to SFStoreCursor, SFSoupQuerySpec renamed to SFQuerySpec, fixed bugs, added native tests
Recreated SalesforfceSDK-*.zip files
Recreated SalesforfceSDK-*.zip files
