improve docs of compiler APIs

hi,

i'm trying to implement an instrumenter on top of typescript compiler APIs.
i cannot find a "real" documentation beside of this wiki page but i think that it should be upgraded from a single wiki page to a dedicated section with examples for:

• creating new nodes (e.g. create a brand new statement and attach it to an existing function body)
• updating existing nodes (e.g. patching a statement)
• add types declarations (e.g. add arbitrary types to a function declaration)
• todo...

what do you think about this?

EDIT: i've found this nice article that shows some really useful code.
EDIT: i've found this nice project that can help to understand how to use the compiler apis for more advanced use cases.

Start with the existing “Using the Compiler API” wiki page and compare it with the linked Scott Logic article and ts-simple-ast project. Define the scope of a dedicated compiler API documentation section, including examples for creating and updating nodes and adding type declarations. Done means the agreed API topics are documented with usable examples.
