ConfigParser class

App configuration parsed from environment variables and command line arguments.

Define configuration parameters first by instantiating ConfigParser and calling setOption then call parse to receive the detected values.

Values are detected in the following order with each step overriding values set by a previous step:

1. default values
2. environment values
3. command line arguments
