collections/map breaks node-red

[biancode]

Hi,

I'm sorry, I've been looking for a problem in my lib and found out that your lib is causing the problem.

BiancoRoyal/node-red-contrib-iiot-opcua#71

require('collections/map') breaks node-red context.global object

It looks like Array.prototype.find has been altered? This is breaking other code as referenced above.
