## range_count_tree.rb
# RangeCountTree
# A bst variant for fast retrieval of count of ranges which are intersecting given n ranges
#
# Creator : Shadab Ahmed
#
# Each node stores a range and the count of intervals which intersect with the range.
#
# We just follow these rules:
# 1. Any range which is greater than the current range is stored in the right subtree
# 2. Any range which is smaller than the current range is stored in the left subtree
