This pull request and prior commits address a number of issues, including:

Saving a copy of the log and config to the results directory
Major restructuring of CalcConfig (and it's JSON representation) into groups of related settings/parameters.
Adding a variety of configuration options related to output and performance. One can now:
- Specify an output directory. If the directory already exists, results are never overwritten in favor of incrementing the output directory with an appended integer.
- Output Poisson probabilities.
- Control the number of system source ruptures that get processed together.
- Control the size of thread pools.
- Control when to flush results to file(s)
- Be more specific about the types of hazard curves to save.
