/**
* Hamcrest Integer matcher with long. Convenient for example in cases like: <br/>
* <code>ResultActions.andExpect(jsonPath("id").value(IntToLongMatcher.equals(testObjectContext.getCcCourtId())))</code>
* in which the value method doesn't allow to put long arg indirectly - in such a case you get something like this:
* <pre>java.lang.AssertionError: For JSON path $.data.parentCourt.id type of value expected:<class java.lang.Long> but was:<class java.lang.Integer></pre>
