R language sdk for rest api documented here https://docs.coinapi.io/

his project is about creating simple SDK in R language for REST API documented at [login to view URL] SDK should have form of a single file class which can be included using GitHub reference and used from some other project. Constructor of class should have one parameter: API Key. For each method of REST API must be defined equivalent method in SDK class. Each class method must be named using snake_case convention. Each class method must cover all REST method parameters and returning JSON deserialized object, method parameters must be aligned with documentation. Along with a class file, there should be example file how to use class like in other language implementations. I would like to you make this project by forking [login to view URL] this repo, and adding `r-rest` directory into it, later when everything will be ok then we will merge into it.
