/**
 * Implementation trait for class <code>FixtureAnyFunSpec</code>, which is
 * a sister class to <code>org.scalatest.funspec.AnyFunSpec</code> that can pass a
 * fixture object into its tests.
 *
 * <p>
 * <a href="FixtureAnyFunSpec.html"><code>FixtureAnyFunSpec</code></a> 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 <code>FixtureAnyFunSpec</code> into some other
 * class, you can use this trait instead, because class
 * <code>FixtureAnyFunSpec</code> does nothing more than extend this trait and add a nice <code>toString</code> implementation.
 * </p>
 *
 * <p>
 * See the documentation of the class for a <a href="FixtureAnyFunSpec.html">detailed
 * overview of <code>FixtureAnyFunSpec</code></a>.
