YAML schema TODOs

• Make
  

  conduit/src/libs/conduit/conduit_node.cpp

  Line 13338 in 92e22b3

  Node::to_yaml_stream(std::ostream &os,

  
  look like
  

  conduit/src/libs/conduit/conduit_node.cpp

  Line 13178 in 92e22b3

  Node::to_json_stream(std::ostream &os,

  
  (Add conduit_yaml, conduit_yaml_external, conduit_base64_yaml) - YAML Schema Part 2 #1335

• Get the final test in t_conduit_generator.cpp to work. - YAML Schema Part 2 #1335

• do the conduit_base64_yaml case - YAML Schema Part 2 #1335

• for conduit_bin based i/o, those paths look for a related .conduit_json file to get schema info.
  Now that we have new fancy yaml schemas, we should also look for related .conduit_yaml file and also wire up their creation. Node::load and Node::save conduit_bin case.

• schema should be able to save to yaml as well

• schema yaml save tests

@cyrush can we move to sharing as much logic as possible between json and yaml methods? Right now we have an awful lot of duplication with to_yaml and to_json methods that share lots of similarities until we get down to the bottom level of the function calls.

I will discuss w/ @cyrush conduit_bin-based i/o
