Allow for math in Pars in config

[oceanlumberjack]

Modify the way that configs are processed to allow simple math (+,-,/,*) in the Par declaration of a config.JSON.

{
    "Sources": {
        "xgraph": "{xgraph}"
    },
    "Modules": {
        "Module": {
            "Module": "Modules.Module",
            "Source": "xgraph",
            "Par": {
                "Parameter": 1/100
            }
        },
        "Deferred": []
    }
}

Could make it a string to eval. Have some type of header “FUN: 1/100” Then calculate anything in the string after FUN:

Could then define

TIME: “FUN: Date.now()”
