Suggestions for the order of the .rst files in the Github

[atefekeshavarzi]

1- Json file, 2- Argument chucker, 3- argument processor, 4- argument miner, 5-argument explorer.

Note that the output of the Json widget is a data framework with columns named 'review text' and 'overall', however the name of the columns in the input of argument chucker are Arguments and score. We have to have the same name in both data frameworks.
