UtilInspectForBrowser

This is NodeJS's util.inspect ported to the browser for usability in other scripts.

Dieses Skript sollte nicht direkt installiert werden. Es handelt sich hier um eine Bibliothek für andere Skripte, welche über folgenden Befehl in den Metadaten eines Skriptes eingebunden wird // @require https://update.greasyfork.org/scripts/450595/1088649/UtilInspectForBrowser.js

// Minified code is scary, so here is the full code for the `inspect` function.
// Please note: Some function names etc. may seem odd, but the file is made realitivly small because of this. This module comes straight from NodeJS and was *compiled* for the browser.
// This means I did not write this code myself (A compiler did!), it was simply compiled to work for the browser.
