Implement new Concept Exercise: static-members

[ErikSchierboom]

This issue describes how to implement the static-members concept exercise for the F# track.

Getting started

Please please please read the docs before starting. Posting PRs without reading these docs will be a lot more frustrating for you during the review cycle, and exhaust Exercism's maintainers' time. So, before diving into the implementation, please read up on the following documents:

• The features of v3.
• Rationale for v3.
• What are concept exercise and how they are structured?

Please also watch the following video:

• The Anatomy of a Concept Exercise.

Goal

The goal of this exercise is to teach the student the basics of the Concept of StaticMembers in F#.

Learning objectives

• Know the difference is between static and instance members.
• Know how to define static methods.
• Know how to define static properties.
• Know how to define static let bindings.
• Know how to define static do bindings.

Out of scope

• Operator overloading.
• ThreadStatic attribute.

Concepts

The Concepts this exercise unlocks are:

• static-members: know the difference is between static and instance members; know how to define static methods; know how to define static properties; know how to define static let bindings; know how to define static do bindings.

Prerequisites

This exercise's prerequisites Concepts are:

• classes: know how to define classes.
• constructors: know how to define do bindings.
• properties: know how to define properties.

Any data types used in this exercise (e.g. strings or integers) should also be added as prerequisites.
