Comment source code functions for intellisense

[ThinkAndWander]

In trying to supply a custom processAllTokens hook:

marked.marked.lexer(stringToParse, { hooks: { processAllTokens: tokens => tokens } })

Typescript wanted hooks to include all the other possible functions the Hooks object can have.

Type '{ processAllTokens: (tokens: TokensList | Token[]) => Token[]; }' is missing the following properties from type '_Hooks<string, string>': options, preprocess, postprocess, emStrongMask, and 2 more.

I eventually determined marked.use({ hooks: { works because it combines the hooks object, making it partial. However, this would've been easier if marked.use mentioned how this works in the intellisense, or if other options did. It's harder to connect the meaning of functions across the app. I think I could've saved a lot of time if the documentation included the source code functions.

(Very excellent software, by the way. I will be using this in my own project.)

If you want to create a PR with what you want the doc comment to say we can review it. It is difficult to add all the information in the docs for each function.

And actually the lexer hooks option is not merged with other hooks. The marked.use one is

Temptinggg. I already considered it, and I still might. I actually did that once for a C# binding of Chipmunk physics, so it wouldn't be my first unprompted PR to a project...we'll see if I'm still thinking about it later :p
