Documentation and examples

1.5.7
Bugfix: getById.exclusive and tryGetById.exclusive did not lock if row was cached.
Improved performance on tryGetFirst.
1.5.6
Raw sql filters can accept sql both as string and as function. E.g. var filter = {sql: function() {return 'foo > 1';}}.

Optional locks for getMany, tryGetFirst and tryGetById. Instead of calling getMany(params) just call getMany.exclusive(params). Same syntax goes for tryGetFirst and tryGetById. This will result in SELECT FOR UPDATE.
