Storage improvement

[Oliviergg]

• Factorize common code in inMemoryStorage and FileStorage => A new class Storage
• Use a JSON to format data to save
• Others params need to be saved : Language, ignore_word, ...
• New test need to be done in 005_inMemoryStorage

Cool :-)

Observation: just did some testing under ruby 2.0.0p247 using the :cat and :dog example where the class names/labels are defined as symbols. When the training set is sent to file storage and then later retrieved in a new process the class names/labels are now returned from #classify as strings instead of the expected symbols.

@MadBomber thanks for the report, I'll test.

Hi @alexandru ,

I trying to save the training set into a text file by below line:

store = StuffClassifier::FileStorage.new('doc/classifier_storage.txt')

and then
cls = StuffClassifier::TfIdf.new("#{row[0]}",:storage => store)

getting error "end of buffer reached"

Any suggestions ?

Thanks
Himanshu
