provide Matcher accepting overloads for IsIn

[GoogleCodeExporter]

IsIn should accept custom matchers, as the counterpart IsCollectionContaining 
does.

So you could do something like that:

assertThat(actualValue, isIn(possibleValues, new ItemMatcher<String>() {
  Matcher<String> apply(String item) {
    return equalToIgnoringCase(item);
  }
}));

(Could be much shorter, with the Java 7 closures, if they will become reality 
one day)

assertThat(actualValue, isIn(possibleValues, 
  #(String item) (equalToIgnoringCase(item)))
);

Best regard,
Daniel

I'm assuming in your test case possible values is just a static array of values:
String[] possibleValues = {"a", "b", "c"};

If this is the case, then is there are reason why your assertion can't be 
expressed by this:

assertThat(actualValue, is(anyOf(equalToIgnoringCase("a"),
                                 equalToIgnoringCase("b"),
                                 equalToIgnoringCase("c"))))

Closing as the requested feature seems achievable via other means and the 
sponsoring user has gone dark.
