Delta downloads don't work (after commit #22)

[mindheist]

Delta downloads now dont work because "download_last_modified.txt" file gets sorted into a folder based on its creation year ,and when the application tries to download it subsequently , it looks for that file in the root folder .

A good way to work around this , might be to have a separate folder for all the application logic files (ie)
creation_date.txt , last_modified.txt and download_last_modified.txt.

the s3_downloads folder already exists , will now selectively download files into this folder

Making the download_last_modified.txt available in the root directory might alone suffice. Tried this manually , and all delta files are being downloaded ( on a side note : make sure that the code to sort and download files is available in all of the loops)

-> The simplest solution for this would be to make the download_last_modified.txt available in the root folder of cloud crate; tested this solution and it seems to work. Tested the following 3 scenarios

1. Download files for the first ever time ( regression test)
   All the files are downloaded into the respective folders and last_modified_time.txt also gets sorted into one of the folders. ( as expected and hence the bug)
   -> All of the application logic files are also created : creation.txt , last_modified.txt
2. Modify just one file , Upload and Download
   -> Modify one file and try to upload
   -> the last_modified.txt gets updated
   -> the creation.txt file get updated
   -> Delta alone gets uploaded based on the information in last_modified.txt
   -> Once again, only the delta is downloaded
3. Add a new file to the directory ; delta alone gets up/downloaded.
