v2.0.0 Iterator arrow operator now returns interval

This is a breaking change!

iter.operator->()
now returns a pointer to the interval, not a node.

The node can now be retrieved via:
iter.node()

Reverted CMake required version bump.

1.3.2

Undid CMake version bump.

Made tests disableable

1.3.1

Made it possible to disable tests.

Project Restructuring

All headers were moved into an include directory.

The directory now provides an interface library that can be used in cmake to inherit the include directory.

Find fix for some tree structures.

1.2

Fixed merge issue and added simple tests.

1.1.1

Fixed cpp version check.

Find All Implemented

find_all and overlap_find_all were added.
overlap_find_next was renamed to find_next_in_subtree and find_next was renamed to overlap_find_next_in_subtree to better reflect their capability.

Performance improvements were made.
