Generate a pseudo-random string which is probabalistically-unique.
Internally, this method uses either the native Buffer from Node.js or the algorithm from the [hat](https://github.com/substack/node-hat) package by [@substack](https://github.com/substack). If you are interested in learning more about psuedo-random number/string generators, you might be interested in reading the Wikipedia list of [random number generator algorithms](http://en.wikipedia.org/wiki/List_of_random_number_generators). Note that, while it is tempting to consider providing a per-process (pseudo-)guarantee of uniqueness by using a process-global "rack" to store past tokens, this module has opted against it in the latest release. This feature was removed to avoid complications around use cases with memory overflow.
