New API. Querying Keys.

[GoogleCodeExporter]

What steps will reproduce the problem?
1.
This doesn't work for me.
            YAML::Node test = node["test"]; <- works
            bool ab = node["test"]; <- does not work

I don't see a bool operator[] in the header. What's the Default way to query in 
the new API.
2.
3.

What is the expected output? What do you see instead?

What version of the product are you using? On what operating system?

Please provide any additional information below.

Ok, Should I use isNull? Like

YAML::Node test = node["test"];
if (!test.isNull()) {
// do something with test?
}

Whoops! This was just a mistake - I seem to have forgotten to implement this. I 
added it, r68cecbc525f9.

The proper way to use it is

   YAML::Node test = ...
    if(test) ...

the check test.IsNull() does something else (a node can be defined but null). 
For example:

    YAML::Node doc = YAML::Load("test: ~");
    assert(doc["test"]);
    assert(doc["test"].IsNull());

Nice catch!
