Detailed Description
This format is a simple text format that's suitable for test data.
The header is a custom format starting with : per line to indicate which codegen data is recorded. # is used to indicate a comment. The subsequent data is a YAML format per each codegen data in order. Currently, it only has a function outlined hash tree.
