Should be able to access previously executed templates/context in a variable template

[mog13]

We should think about passing in some sort of context when a variable token is executed. This would allow functions to make decisions based on a previous templates outcome. I'm thinking along the lines of:

Splain.addEntry({colors:["red","green","blue"]});

let getCol = (context) =>{
    if(context.someWayToGetPreviousToken === "red") return "#ff0000";
    if(context.someWayToGetPreviousToken === "green") return "#00ff00";
    if(context.someWayToGetPreviousToken === "blue") return "#0000ff";
    return '#ffffff';
};

console.log(Splain.process("why not try {{colors}} ({{##getCol}})",{getCol}));
