Code Kata: Recently opened files

Kata #2: Recently opened files
 
Implement a container that has the well known functionality of "Recently opened files" that you know from various applications you use:
  • the container must be able to list file paths that it stores
  • if file A is opened and right after that we ask the container to list the file paths it stores, the path to file A will be listed as the first one
  • the number of stored file paths is limited; when the limit is exceeded the container forgets least recently used file path
  • in the list of recently open files, each file path can appear once and only once
