A heap is a binary tree satisfying the following
conditions:
This tree is completely balanced.
If the height of this binary tree is h, then leaves
can be at level h or level h-1.
All leaves at level h are as far to the left as
possible.
The data associated with all descendants of a
node are smaller than the datum associated
with this node.
This the beta version of the Christmas tree rendering whitepaper. A final version
