Make "process" a required input and configure pyconf functions globally once with user input

Closes #59 (closed) and closes #74 (closed).

• Make process a required input.
• Make "options.process" as the default input to algorithms (e.g. truth matching).
• Make process a required input to truth-matching algorithm (related to issue: #62 (closed)) and also set correct root-in-tes for Turbo process.

To be tested with: LHCb!3806 (merged), Moore!1812 (merged) and Analysis!914 (merged)
