Need for documentation

[dluc]

For a new adopter, aside from the examples, it's quite hard understanding how to configure the engines. There are a few areas that could use some extra docs:

• types.cs: documenting all the properties, explaining what they do, when to change them
• add more comments in the examples, explaining what each line is doing and why
• organize examples in 2 groups: configuring engines programmatically vs configuring engines via YAML files
