Survey form configuration

[twinkarma]

I propose the use of a form configuration represented by JSON, similar to what was done with Teamware but doesn't have to be as complicated. Configurations are stored as a json field the Survey model.

When responding to a survey, this configuration is used to build the form and shapes the output structure of our responses. The responses of the surveys can also be stored as a json field an the Response model.

See the following board for more detail:

e.g. here's a basic configuration with 1 section and 2 questions in the section:

{
  "name": "Survey name",
  "description": "Description",
  "children": [ 
    {
      "type": "section", 
      "name":"Section name",
      "description": "Section description",
      "sectionType": "SORT",
      "children": [
        {
          "type": "text",
          "title": "Field title",
          "description": "Field description",
          "validation": "some regex",
          "defaultValue": "Default text",
          "isRequired": true
        },
        {
          "type": "likert",
          "title": "Please give a score",
          "options": [0, 1, 2, 3, 4],
          "isRequired": true
        }
      ]
    }    
  ]
}

Looks like django's Form class doesn't support dynamically adding fields. Probably best into either look into using the FormSet class or just roll our own form validator.
