Implement PDF/DOCX timetable generator

[wingsofovnia]

The main export format of hermes will be a GTFS format. All other exports will be based on the transformation of exported GTFS package then.

The most important automation in Hermes is schedule tables export. That means we need to implement a mechanism of creating schedules tables from GTFS. These reports are published on bus stops in a paper form then.

Some basic requirements:

• Input: gtfs zipped package
• Output: pdf or any editable open doc format (docx / odt etc.)
• Schedule templates must be separatable from generation code, i.e. when a new schedule design comes, we will be able to update generator will minimal effort
• Ideally - have such templating mechanism they can handle by their own, i.e. they will be able to edit templates and import them to the generator.
  I heard about JasperReports from Java world. It even has IDE for creating reports incl document templates. There is a python binding https://github.com/jadsonbr/pyreport. Im not sure if it's a right tool for this task, research needed.
• REST API

Some milestones:

• Get to know with GTFS (required files only) https://developers.google.com/transit/gtfs/reference/
• Search for available GTFS parsers and processors. Choose one or implement own.
• Search for available pdf/docx tools with templating. Choose one.
• HelloWorld with schedule template
• Initial implementation, demo

To simplify and speed-up dev, we will use direct schedule 2 pdf generation. At least for the first iteration.
