Check_IsUsable(bool throwErrs)
const
Description
The CheckIsUsable method verifies if an object is in a usable state; unlike get_IsUsable, it will check if any necessary support files are missing, and update's the object's internal usability property accordingly. It takes in a bool that controls whether the method should throw exceptions and, if it is enabled, will return a GeoCalcExeption if it encouters a problem.
