Feature/add typed method list abbreviation

[unnamedunknownusername]

WIP for #150

Essentially just copying the code from MethodList and creating TypedMethodList

Then inserting a copy of a section of typed signatures into the right spot

@MichaelHatherly, let me know if I have missed anything

I have added a section in the tests for typed method list testset. But I am thinking we probably need more/want more comprehensive ones

Also how can I run the tests locally/verify that the ones I add are passing.

Sorry if those are simple questions, just having a little difficulty with this part
