0.3

Various fixes (PR #4) from @christolliday. Main breaking change is that variables no longer silently initialise to zero and will report their initial value in the first call to fetch_changes, also has_edit_variable now takes &self instead of &mut self.

0.2.1

Fixed crash under certain use cases. See PR #1 (Thanks @christolliday!).

0.2.0

Changed API to only report changes to the values of variables. This allows for more efficient use of the library in typical applications.
