We need to add `switch`, `case`, and `default`.
We don't yet use these, but they should be the kind of thing that we need. We have two sections: * One for the "switch .." which contains a series of * "case ..." expressions, one of which may be a default.

Once complete this pull-request will implement support for
switchstatements, which will close #70.Our switch statement will allow an arbitrary number of
caseexpressions, allowing different blocks of code to be executed depending upon the match.We allow one
defaultbranch in case nothing matches, but this is optional (it is an error to have multipledefaultcases).Note that we avoid any confusion with C due to using blocks explicitly, there can be no "fall-thru".
