/**
* Implementation trait for class FlatSpec, which facilitates a
* “behavior-driven” style of development (BDD), in which tests
* are combined with text that specifies the behavior the tests verify.
*
*
* FlatSpec 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 FlatSpec into some other class, you can use this
* trait instead, because class FlatSpec does nothing more than
* extend this trait and add a nice toString implementation.
*
*
*
* See the documentation of the class for a detailed
* overview of FlatSpec.
