add more refactoring tools

[regisp]

Hi,

I'd really love to see refactoring tools such as

• implement interface
• extract method

come in typescript (at least for visual studio 2015).

Many thanks for your work!

I would also like to see this as it would make the development experience much better.

Can we also have move method?

I asked a question on reddit related to this. Would be very grateful to get a response from someone at Microsoft. https://www.reddit.com/r/typescript/comments/54bzah/friendly_typedclassbased_representation_of/

What I'd love for VS2015 is refactoring tools for:

• Implementing abstract classes
• Generating the constructor of subtypes

These are basics that would bring a massive improvement to the development experience.
