/**
 * Entry point for assertion methods for different types. Each method in this class is a static factory for a
 * type-specific assertion object.
 * <p>
 * For example:
 *
 * <pre><code class='java'> int removed = employees.removeFired();
 * {@link Assertions#assertThat(int) assertThat}(removed).{@link IntegerAssert#isZero isZero}();
 *
 * List&lt;Employee&gt; newEmployees = employees.hired(TODAY);
 * {@link Assertions#assertThat(Iterable) assertThat}(newEmployees).{@link IterableAssert#hasSize(int) hasSize}(6);</code></pre>
 * <p>
 * This class only contains all <code>assertThat</code> methods, if you have ambiguous method compilation error, use either {@link AssertionsForClassTypes} or {@link AssertionsForInterfaceTypes}
 * and if you need both, fully qualify you assertThat method.
 * <p>
 * Java 8 is picky when choosing the right <code>assertThat</code> method if the object under test is generic and bounded,
 * for example if foo is instance of T that extends Exception, java 8  will complain that it can't resolve
 * the proper <code>assertThat</code> method (normally <code>assertThat(Throwable)</code> as foo might implement an interface like List,
 * if that occurred <code>assertThat(List)</code> would also be a possible choice - thus confusing java 8.
 * <p>
 * This why {@link Assertions} have been split in {@link AssertionsForClassTypes} and {@link AssertionsForInterfaceTypes}
 * (see http://stackoverflow.com/questions/29499847/ambiguous-method-in-java-8-why).

   *
   *   private boolean blinking;
   *
   *   public boolean isBlinking() { return this.blinking; }

   *     assertThat(button.isBlinking()).isTrue();

   *   MyButton button = new MyButton();
   *   MyButtonAssert buttonAssert = new MyButtonAssert(button);

   *   assertThat(buttonAssert).isNotBlinking(); // same as : buttonAssert.isNotBlinking();
   *
   *   button.setBlinking(true);
   *
   *   assertThat(buttonAssert).isBlinking(); // same as : buttonAssert.isBlinking();
