Test cases not using just the indicated functions

[ocelotsloth]

Many of the test cases are using the full calendar api, which makes it difficult to isolate individual problems. If, for example, a test case dealing with event generation directly called the generate() function it would make things much simpler to diagnose and write test cases for.

I'll be the first to admit that this is a pretty large undertaking.

Roger that, it's very frustrating, but I don't plan to change this in ical-generator 2.x.
But it's on my list for 3.x - sorry…
