    To test use the following specification for Shiftr ensure that spec is 
valid:
    
    `{
          "\\@context": {
            "name": "&1.Name",
            "ingredient": "&1.Inputs",
            "yield": "\\@context.Makes",
            "*": "&1.&"
          },
          "name": "Name",
          "ingredient": "Inputs",
          "yield": "Makes",
          "*": "&"
        }
     `
    
    Also the below test input can be used in the Advance (from 
http://jolt-demo.appspot.com/#json-ld-escaping)
    
    `{
      "comment" : "pulled from http://json-ld.org/playground/ example recipe.  
Also, Mojitos are good.",
    
      "@context": {

      },
      "name": "Mojito",
      "ingredient": [
        "12 fresh mint leaves",
        "1/2 lime, juiced with pulp",
        "1 tablespoons white sugar",
        "1 cup ice cubes",
        "2 fluid ounces white rum",
        "1/2 cup club soda"
      ],

        },
        {
          "step": 3,
          "description": "Pour white rum over ice."
        },
        {
          "step": 4,
          "description": "Fill the rest of glass with club soda, stir."
        },
        {

>          Components: Core Framework
>    Affects Versions: 1.0.0
>            Reporter: Yolanda M. Davis
>            Assignee: Yolanda M. Davis
>             Fix For: 1.0.0
>
>
> The following jolt spec failed to pass the validation check in 
> JoltTransformJSON:
>     {
>       "\\@context": {
>         "name": "&1.Name",
>         "ingredient": "&1.Inputs",
>         "yield": "\\@context.Makes",
>         "*": "&1.&"
>       },
>       "name": "Name",
>       "ingredient": "Inputs",
>       "yield": "Makes",
>       "*": "&"
>     }
> The reason is the double backslash to escape '@' which should be supported to 
> identify literal characters.
> Upgrading to Jolt version 0.0.21 should resolve this problem since it was 
> fixed in that release.
