59e85a379d Added flushInstance() method to clear the calculation cache, but only if the calculation engine has been instantiated. 
Moved precision setting from functions.php to the calculation engine constructor, with a reset when the calculation engine instance is unset... will be of value when I switch the code to support a calculation engine/cache with each instantiated PHPExcel object.
