Add new exercises errors5 and errors6, to introduce boxed errors and custom error enums more gently. Delete errorsn, because it tried to do too much too soon. |

Error handling
Most errors aren’t serious enough to require the program to stop entirely. Sometimes, when a function fails, it’s for a reason that you can easily interpret and respond to. For example, if you try to open a file and that operation fails because the file doesn’t exist, you might want to create the file instead of terminating the process.
