Features

• Planning ability for general Role through _plan_and_act function
• A CodeInterpreter(Role) that could solve problems through coding. This role inherits the planning ability and can also use tools.
• A MLEngineer(Role) that tailored for machine learning and data analysis
• Both roles above can interact with human for plan confirmation or modification
• A Planner and a data structure Plan were the support for role's planning capability.
• Multiple Actions reusable across roles, incluing WriteCodeByGenerate, WriteCodeWithTools, ExecuteCode, etc. These enable a real-time code generation and display.

2. Notice that some logic has actually changed boundaries in the modification and need to provide a test result
