    * [x] The global tasks table
    * [x] The framework-specific task table (when clicking into a framework)
    * [x] The executor-specific task table within an agent (when clicking into 
an agent, then a framework, then an executor)
    
    > I'm also a bit curious about whether it's a good idea to re-use the 
health string as a class, since it seems easy to break vs only specifying the 
display string in the html page.
    
    I removed CSS. I'm not sure if red/green looks good in Mesos blue palette. 
@lilysamimi Any idea how to present health state?

    I used Marathon to deploy 3 applications with 3 types of health state.
    
    ```
     curl -X PUT -d@health_groups.json localhost:8080/v2/groups/
    ```
    
    ```json
