> This ticket will add test functions in Worker and Driver classes.
> These functions will provided two functionalities,
> 1. test the performance of a previously trained model, whose parameters are loaded from checkpoint files. 
> 2. extract the features from some middle layers of the neural net. The input data does not have labels. To extract features from one layer, an output layer would be added after this layer. Two output layers will be implemented at first 
>     * ProtoRecordOutpuLayer which writes the feature as SingleLabelImageRecord into KVFile
>     * CSVRecordOutputLayer which writes the feature as CSV line into TextFile.
