[Tutor] Create command

[Steve Willoughby]

Ok, that’s good. Now try putting that in a loop so it asks over and over, then look at changing if from the question of name and age to the commands the assignment is asking for.

It’s not clear from the problem given whether they want you to permanently store the data so if you restart the program you still have all the data stored previously, or just need to hold it in memory for retrieval during the same run of the program.

In other words, given a key and a value, which are both strings, it can store key and value together, and then return that value when fetched by that key. The tool must be able to be run from the command line by typing "key-value", though it is acceptable to also require the path or an extension (eg, "./key-value.rb" is fine). If needed, it is acceptable to include a setup script that must be run before the tool can be run. Running the tool must open an interactive session that accepts put, fetch, and exit commands. When ready to accept a command, it must output the string "> " as a command prompt.
