Document expected results for all learning_cp examples

[jardinetsouffleton]

As of now the examples in the learning_cp section all run successfully, but the expected results are not known or documented. Having this information would make it easier for new users to know that they are doing the right thing when building models/solving problems. The goal here is:

• To run all examples in learning_cp and confirm they are learning properly
• Fix examples having low performance by adjusting hyper-parameters/architectures used, etc
• Write documentation about the expected behavior of the learning_cp examples
