Support embedded/referenced object validation

[mavarazy]

Currently this objects are ignored by the validator

Will this allow for referencing other nested properties in the form object? I'm currently trying to figure out how to compare two properties I have on an object that I have a schema for.

var diffPercent = function(first, second){
    return (second-first)/first * 100;
}

predicate.decreasedByMoreThanPercent = predicate.curry((val, params) => {
    return predicate.num(val) &&
        predicate.num(params.average) &&
        predicate.num(params.target) &&
        predicate.less(val, params.average) &&
        predicate.greaterEq(Math.abs(diffPercent(val, params.average)), params.target);
});

var rules = [{
    conditions: {
        cost: {
            decreasedByMoreThanPercent: {
                average: "averages_monthly.cost",
                target: 20
            }
        }
    },
    event: {
        type: "whatever",
        params: {
            field: "something"
        },
    }
}];

var schema = {
    definitions: {
        averages_monthly: {
            type: "object",
            properties: {
                cost: { type: "number" }
            }
        }
    },
    properties: {
        cost: { type: 'number' },
        averages_monthly: {
            $ref: "#/definitions/averages_monthly"
        }
    }
};

var formData = {
    cost: 50,
    averages_monthly: {
        cost: 100
    }
}

@CodestarGames As I understand you want to have a condition looking something like

 conditions: {
     cost: {
        decreasedByMoreThanPercent: {
             average: "averages_monthly.cost",
             target: 20
         }
     }
 }

This specific issue, is not for that. This is for validating references like "averages_monthly.cost", that averages_monthly actually has a cost field. This can be a good feature, I'll open a separate issue to address this.

@CodestarGames I've fixed #14, so now it should work, by appending $ to the field definition, like this.

 conditions: {
     cost: {
        decreasedByMoreThanPercent: {
             average: "$averages_monthly.cost",
             target: 20
         }
     }
 }

The fix is in the latest release 0.1.11
