Replace print() in documentation

[niccokunzmann]

The print statement in the documentation has been modified. However, this causes confusion.

Current solution

• to convert bytes to string - Python 2 compatible
• provide an easy way to display the resulting component as ics

Current Problems

• when you copy & paste the code, you get a different output
• that can be confusing

Future ideas

I would like people to be able to view and see, grasp and have documented well the resulting ICS output and calendar.

• it would be nice to use ics syntax highlighting on the <output>
• it would be nice to do something like this in the docs:

>>> from icalendar import Calendar
>>> calendar = Calendar.new()
>>> calendar.view()
<output>

• When using the above statement, what I would like to be able to switch between ics and jcal output in the documentation, like sphinx-icalendar.

Implementation

• test/conftest.py needs changing
• if we go with view(), then, this goes into Component
• A new solution should solve the problems and discuss the best way forward for the ideas
