Add main.go with configuration

Set up a configuration object which gets read from a YAML config file.

Currently using an uncommitted test file that looks like this (with some
data filled in:

    auth:
      username:
      password_cmd:

    fields:
      person_id:
      clients:
        - id:
          name:
          projects:
            - id:
              name:
              modules:
                - id:
                  name:
              tasks:
                - id:
                  name:
              work_types:
                - id:
                  name:

The program just outputs the config object so I can see whether it's
working. The data will then be used to associate ids for time
submission.
