modified sis_upload.rb to do:

1. read from command line of the token file and server name respectively. Here is the example to invoke the ruby file:

ruby ./SIS_upload.rb <the_token_file_path> <the_server_name>

2. writes to output file in ./output/Canvas_Extract_<timestamp>.txt file.

3. moves the anvas_Extract_<timestamp>.zip file to ./archive/ folder.
