Refactor the Geo LogCursor Logger to make class more descriptive

What does this MR do?

To make the source class more descriptive, i.e. including all the parent module names, the Logger used by the Geo LogCursor is refactored to be a class. The caller should instantiate it and pass it it's class so the logger can extract it's name.

Are there points in the code the reviewer needs to double check?
