/**
 * See {@link Matchers} for general info about matchers.
 * <p>
 * AdditionalMatchers provides rarely used matchers, kept only for somewhat compatibility with EasyMock. 
 * Use additional matchers very judiciously because they may impact readability of a test.
 * It is recommended to use matchers from {@link Matchers} and keep stubbing and verification simple.
 * <p>
 * Example of using logical and(), not(), or() matchers: 
 *  
 * <pre class="code"><code class="java">
 *   //anything but not "ejb"
 *   mock.someMethod(not(eq("ejb")));
 *   
 *   //not "ejb" and not "michael jackson"
 *   mock.someMethod(and(not(eq("ejb")), not(eq("michael jackson"))));
 *   
 *   //1 or 10
 *   mock.someMethod(or(eq(1), eq(10)));
 * </code></pre>
 * 
 * Scroll down to see all methods - full list of matchers.
