Simplify the usage of Matchers.empty()

[GoogleCodeExporter]

Currently it is nearly not possible to use #empty() as a static import, because 
of its generic return type.

Currently we have to write something like this in a JUnit-Testcase...

Set<String> strings = ...
assertThat(strings, is(Matchers.<String>empty());

it is easier to read if we could use a static import...

Set<String> strings = ...
assertThat(strings, is(empty());

this could be done if IsEmptyCollection#empty() would look like this..

public static Matcher<Collection<?>> empty(){
 return new IsEmptyCollection();
}
