Launch Pathfinder queries from ARAX UI

[isbluis]

We have added a draft implementation for quickly launching PF queries via our UI. It is only a first draft, so I would not characterize it as a final version, but hopefully gives us the ability to test various queries as well as the rest of the system, including responses.

The step-by-step guide (with a couple of open items to resolve) :

1. Go to the UI in devLM: https://arax.ncats.io/devLM/

2. Find and click on the new button under the build-a-graph section:
   

3. This will create the "triangle" and display a pop-up to edit the target node (n2); enter a CURIE

4. Important! Once the CURIE has been entered, click to remove the Category so that it is empty:
   

5. Click on the source node on the graph (n0), and do the same as above (i.e. enter a CURIE and remove its Category)
   

6. Optional: edit the Category of the intermediate node n1 by clicking on it and adjusting as desired.

7. Submit by clicking on the Query ARAX button. Note that it may take a while for the response to appear.

The main issue is that the query will cause an error if a Category is specified for either the source or target node. @dkoslicki , is this a hard requirement?

Another issue is the paucity of user feedback during the processing; not sure if it is feasible to add some. As it is, there is a long pause between the initial message parsing and the response generation.

Please test when convenient, and report issues here; hope it helps!

@mohsenht , can you comment on this? IIRC, specifying the category should be totally fine, right? Perhaps this is just a DSL issue not accounting for categories possibly being provided?

I created a bug for this issue, the issue is from my side.
