/**
* Implementation trait for class WordSpec, which facilitates a “behavior-driven” style of development (BDD), in which tests
* are combined with text that specifies the behavior the tests verify.
*
*
* WordSpec is a class, not a trait, to minimize compile time given there is a slight compiler overhead to
* mixing in traits compared to extending classes. If you need to mix the behavior of WordSpec
* into some other class, you can use this trait instead, because class WordSpec does nothing more than extend this trait and add a nice toString implementation.
*
*
*
* See the documentation of the class for a detailed overview of WordSpec.
