(#37) * Create ColFamilyReadOnly and ColFamilyReadWrite types for using a specific column family. * Use inline pragma for small procs and add lock to RocksDbRef type close to prevent double free. * Added documentation for the public API. * Initial implementation of sst filewriter. * Added tests for sstfilewriter. * Documentation minor improvements.
