added hill climbing sample and custom nodes needed for sample from post 4
changed package file to include custom nodes for sample in post 4
added a test that checks results of the recursive hill climbing using xyz distance to verify the correct result.
note that I was not sure on best practices for referencing samples and custom nodes needed to run the test so I referenced them directly from the samples and dyf folders.
changed custom nodes to use no python so this test does not time out.
added Rendering_hill_climbing_simple() test to the DynamoRevitTests.xml
