the list-inspectors command shows a list of available inspectors as well as the active inspectors in the list. inspectors are drawn with a name as well as a short description. change-inspector can be used to change the inspector by the name found in the list-inspectors command. an inspector in pry is something that prints a return value in a repl session. i'm not crazy about the name `inspector` but the traditional name used in pry(`print`) didn't fit well. some discussion led us to `inspector` for lack of a better word, see #1176 on github for discussion
