Function PropertyPath

Example

import PropertyPath from "apprt-core/PropertyPath";

let path = PropertyPath("a.b.name");

// parser errors are reported by "invalid" property
if(path.invalid){
     ...
}

let target = {
 a: {
     b: {
         name: "test"
     }
 }
};

let accessor = path(target);
accessor.invalid // -> false, but true if path is not accessible in target
accessor.exists() // -> true, b hasOwnProperty name
accessor.get() //-> "test"
accessor.set("new val") // -> changes target.a.b.name to "new val", will throw an error if property is not accessible
