* Concatenates the values of a variable into an easily readable string

* @param {Object} x The variable to debug
* @param {Number} max The maximum number of recursions allowed (keep low, around 5 for HTML elements to prevent errors) [default: 10]
* @param {String} sep The separator to use between [default: a single space ' ']
* @param {Number} l The current level deep (amount of recursion). Do not use this parameter: it's for the function's own use
