 ## Lib: Error Handling
 Error handling in Laika is done via the 'lerror.h' header library. It's a small and simple error handling solution written for laika, however can be stripped and used as a simple error handling library. Error handling in Laika is used similarly to other languages, implementing a try & catch block and is achieved using setjmp(). The LAIKA_ERROR(...) is used to throw errors.
