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

   * An immutable Set of test names. If this AnyWordSpec contains no tests, this method returns an
   * empty Set.
   *
   * 
   * This trait's implementation of this method will return a set that contains the names of all registered tests. The set's
   * iterator will return those names in the order in which the tests were registered. Each test's name is composed
   * of the concatenation of the text of each surrounding describer, in order from outside in, and the text of the
   * example itself, with all components separated by a space. For example, consider this AnyWordSpec:
   * 
   *
   *    * import org.scalatest._
   *
   * class StackSpec {
   *   "A Stack" when {
   *     "not empty" must {
   *       "allow me to pop" in {}
   *     }
   *     "not full" must {
   *       "allow me to push" in {}
   *     }
   *   }
   * }
   * 
   *
   * 
   * Invoking testNames on this AnyWordSpec will yield a set that contains the following
   * two test name strings:
   * 
   *
   *    * "A Stack (when not empty) must allow me to pop"
   * "A Stack (when not full) must allow me to push"
