Add support for cell locators to the probe filter
This issue was created automatically from an original Mantis Issue. Further discussion may take place here.
There are situations where FindCell can fail due to its use of point locators. This is specially an issue in grids that are not topologically well connected such as mesh refinement grids (unstructured) that have hanging nodes. Given the option to use a cell locator should address such cases. In fact, it may be a good idea to investigate using cell locators as the only option if the performance overhead is not large.
