test site

[YuWei-CH]

1. Add route on /test
2. Modify run.sh to support the use of the local ref sequence
3. Add a dictionary to app.py's submit() function to hold the address of the name of the local file.
4. Add the upload_test and verify_test_uploads functions to job.py to create soft links to local files
5. I didn't upload the local test files such as ref_fasta, upstrea_fa to github because of their large size, I will manually transfer the files to the production site folder and set gitignore.
