You will need to implement a class that satisfies the interface. The methods are specified here:
http://docs.racket-lang.org/tools/drracket_language.html?q=sgn#%28def._%28%28lib._drracket%2Ftool-lib..rkt%29._drracket~3alanguage~3alanguage~3c~25~3e%29%29 (see all the indented specs). For some of them, it's probably okay to give no-action implementations.
