Concat decorator implementation appears wrong

[codeandcats]

I was poking around the any constraints and noticed that Concat looks like it's possibly implemented incorrectly. As you can see schema is declared twice.

/**
 * Returns a new type that is the result of adding the rules of one type to another.
 */
export function Concat(schema : Schema) : PropertyDecorator {
    return constraintDecorator([], (schema : Schema) => {
        return schema.concat(schema);
    });
}

I suspect this should be:

/**
 * Returns a new type that is the result of adding the rules of one type to another.
 */
export function Concat(schema : Schema) : PropertyDecorator {
    return constraintDecorator([], (existingSchema : Schema) => {
        return existingSchema.concat(schema);
    });
}

Empty seems to be the same:

/**
 * Outputs the original untouched value instead of the casted value.
 */
export function Empty(schema : any) : PropertyDecorator {
    return constraintDecorator([], (schema : Schema) => {
        return schema.empty(schema);
    });
}

@laurence-myers if you agree I'm happy to create a PR with the fix.
