A veg-modifier-model-run-prototype is created

[ruiwu1990]

1. http://192.168.99.100:5010/scenario_table is the main page
2. The basic workflow is that users go to /scenario_table to create a scenario or view an existing scenario. If users choose to create one, then the system will go to http://192.168.99.100:5010/create_new_scenario, a list of model runs will be shown in a table. Users use a 2D map tool to modify veg variables; Give scenario a name; Run scenario; system redirect users to the main page and the new created scenario will be shown in the table.
3. Users need to have at least a model run in Moinul’s server. This is because the workflow. This will cause a problem (have no model run to create a scenario), if you are a new users and do not have any model runs in Moinul server, you may go to http://192.168.99.100:5010 to create a model run.
4. I have done a small test that different scenarios are different: change all the HRU into bare ground vs shrub, the hydrographs are different
5. You may have a problem with authorization if you use Chrome instead of FireFox. I do not know why some times Chrome complains the API key (JWT authorize) expired but FireFox never does that.

TODO:

1. In http://192.168.99.100:5010/create_new_scenario, only display finished model run
2. Add authorization in the system.

This isn't ready for a merge yet, there are quite a few problems. In general I need you to be more careful submitting pull requests: don't include errant data and please follow style standards. Also make sure to merge the current master branch before opening pull requests.

Also, it appears you are developing with a Dockerized version of the system. Please include instructions both on how to run Docker and how to work with the code running in the Docker container.

Regarding 3)

Users need to have at least a model run in Moinul’s server. This is because the workflow. This will cause a problem (have no model run to create a scenario), if you are a new users and do not have any model runs in Moinul server, you may go to http://192.168.99.100:5010 to create a model run.

This won't work. There has to be a default, pre-initialized set of inputs to use. We have to enable new users to get going even if they don't have data ready.

I tried to merge the latest master branch, but I found you have deleted 'PRMSCoverageTool.py'. I have modified this file and use some functions in this file. Can you let me use this file for current version? 3. is fixed. Users do not need to have inital model run.

The scenario tool doesn't seem to be working for me. I followed your instructions and tried to create a new scenario.

When I navigate to /create_new_scenario I see the screen below:

However in the console there is an error. Here's the traceback:

When I click the "Choose Me" nothing happens and there is another error in the console. Here is the request and traceback:
