Edit the app routes

Is your feature request related to a problem? Please describe.
The current routes includes exercise which doesn't make sense. Basically the current for example/exercise/3 route is just a symntathic sugar that hides searchParams like pausePlaces .
Describe the solution you'd like
Lets repair that! we should add a new searchParam for handling storing the therapist choice of pointer's pausePlaces. Also it would be nice to add a new route that will store a therapist name/nickname so the final URL will look like:

https://www.treefrog-vision.com/JohnSmiths?iterationTime=30s&delay=5s&pausePlaces=topLeft&pausePlaces=topCenter&pausePlaces=topRight

As you can see now we are more specific in describing the exact place (now it is 2-dimentional (upperRight/UpperLeft... location not just the 1-dimentional like now (left/right). It will be also nice to change the exercise logic to support the brand new pausePlace. It might also require to refactor the Directions enum or at least to create a bew additional one.

Additional context
This might be helpful:

let params = new URLSearchParams();
params.append('arrayparams', 'val1');
params.append('arrayparams', 'val2');
params.append('arrayparams', 'val3');
console.log(params.toString());

It will be nice to create this one before the #183 ! It will be easier that way.

Keep in mind that we will have more different exercises so exercise param will be useful the only thing is that instead of placing just a plain number it will be better to name exercise and store it value s as string.

In other word I think that this one can be easily closed.
