Determine if two line segments intersect (not lines!)
# R functions to determine if two line segments intersect
# Note: this is very different question from whether
# two lines intersect (terminology is important!)
# These functions are based upon the excellent discussion here,
# written by Martin Thoma:
# martin-thoma.com/how-to-check-if-two-line-segments-intersect/
# The starting point was the code here:
# github.com/MartinThoma/algorithms/tree/master/crossingLineCheck/Geometry/src
