Error Handling

• In cases where a user writes an "invalid program" (picture using variables that have not been defined yet), we want to make sure that we stop interpreting
• Similarly, we don't want our interpreter to "Panic" - try to aim for something similar to Python where they give you a descriptive message about why your interpreter cannot continue
• " is not defined." would do wonders
• Do a quick audit of where you've called "unwrap" and make sure that these are really scenarios where errors cannot occur contextually
