 * Checks if one {@code Class} can be assigned to a variable of another
 * {@code Class}.

 * Unlike the {@link Class#isAssignableFrom(java.lang.Class)} method, this
 * method takes into account widenings of primitive classes and {@code null}

 * <p>
 * Primitive widenings allow an int to be assigned to a long, float or

 * 
 * <p>
 * {@code Null} may be assigned to any reference type. This method will
 * return {@code true} if {@code null} is passed in and the toClass is
 * non-primitive.
 * </p>
 * 
 * <p>
 * Specifically, this method tests whether the type represented by the
 * specified {@code Class} parameter can be converted to the type
 * represented by this {@code Class} object via an identity conversion
 * widening primitive or widening reference conversion. See
 * <em><a href="http://docs.oracle.com/javase/specs/">The Java Language Specification</a></em>
