 /**
 25  
  * Truth - a proposition framework for tests, supporting JUnit style 
 26  
  * assertion and assumption semantics in a fluent style.
 27  
  * 
 28  
  * Truth is the simplest entry point class. A developer can statically
 29  
  * import the ASSERT and ASSUME constants to get easy access to the 
 30  
  * library's capabilities. Then, instead of writing:
 31  
  * <pre>{@code 
 32  
  * Assert.assertEquals(a,b);
 33  
  * Assert.assertTrue(c);
 34  
  * Assert.assertTrue(d.contains(a) && d.contains(e));
 35  
  * Assert.assertTrue(d.contains(a) || d.contains(q) || d.contains(z));
 36  
  * }</pre>
 37  
  * one would write:
 38  
  * <pre>{@code 
 39  
  * ASSERT.that(a).equals(b);
 40  
  * ASSERT.that(c).isTrue();
 41  
  * ASSERT.that(d).contains(a).and().contains(b);
 42  
  * // or
 43  
  * ASSERT.that(d).containsAllOf(a, b);
 44  
  * ASSERT.that(d).containsAnyOf(a, q, z);
 45  
  * }</pre>
 46  
  * 
 47  
  * Tests should be easier to read, and flow more clearly.
