Surveysystem: Test /analyse endpoint

test-analyse.sh

#!/bin/bash

## performs two calls to /analyse for a given session and compares responses. 
## If both match the test passes. 
## If a mismatch occurs or a single response is invalid then the error and the response will be logged into ./error.log
## Tests are repeated 50 times.
