Log Message:
py-intervaltree: updated to 3.0.2

Version 3.0.2
- Fixed:
  - On some systems, setup.py opened README.md with a non-unicode encoding. My \ 
fault for leaving the encoding flapping in the breeze. It's been fixed.

Version 3.0.1
- Added:
  - Travis testing for 3.7 and 3.8-dev. These needed OpenSSL, sudo and Xenial. \ 
3.8-dev is allowed to fail.
- Fixed:
  - PyPI wasn't rendering markdown because I didn't tell it what format to use.
  - Python 2 wasn't installing via pip because of a new utils package. It has \ 
been zapped.
- Maintainers:
  - TestPyPI version strings use .postN as the suffix instead of bN, and N \ 
counts from the latest tagged commit, which should be the last release
  - Install from TestPyPI works via make install-testpypi

Version 3.0.0
- Breaking:
  - search(begin, end, strict) has been replaced with at(point), overlap(begin, \ 
end), and envelop(begin, end)
  - extend(items) has been deleted, use update(items) instead
  - Methods that take a strict=True/False argument now consistently default to \ 
strict=True
  - Dropped support for Python 2.6, 3.2, and 3.3
  - Add support for Python 3.5, 3.6, and 3.7
- Faster Interval overlap checking
- Updated README:
  - new restructuring methods from 2.1.0
  - example of from_tuples() added
  - more info about chop(), split_overlaps(), merge_overlaps() and merge_equals().
- Fixes:
  - Node.from_tuples() will now raise an error if given an empty iterable. This \ 
should never happen, and it should error if it does.
  - Interval.distance_to() gave an incorrect distance when passed the Interval's \ 
upper boundary
  - Node.pop_greatest_child() sometimes forgot to rotate() when creating new \ 
child nodes.
  - IntervalTree.begin() and end() are O(1), not O(n).
  - intersection_update() and symmetric_difference() and \ 
symmetric_difference_update() didn't actually work. Now they do.
  - collections.abc deprecation warning no longer happens
- Maintainers:
  - PyPi accepts Markdown! Woohoo!
  - reorganize tests
  - more tests added to improve code coverage (We're at 96%! Yay!)
  - test for issue 4 had a broken import reference
