Easier value-parameterized test API

[GoogleCodeExporter]

The current API requires constructing a class for my value parameterized test 
and then instantiating it with another macro. I would like to see a shortcut. 
For example:

TEST_PI(MyTestCase, MyTest, int, Values(1, 2, 3, 4))
{
    int param = GetParam();
    // ...
}
