Title: Added updateGeometry() function to dynamically update geometry

When using ParametricGeometry, geometry is created from a passed in function. If this function is based on parameters that change, there is no good way to reevaluate geometry. I propose a new function

```
ParametricGeometry.updateGeometry()
```

which resets all geometry based on a reevaluation of the constructing function.
