Addition of is_line_optimization boolean member variable in object
of class Polychainline_2. Suppose this variable of an obect is set
to true. If this object is tried for an intersection with another
Polychainline object pcl, using the function
first_intersection_point_with, then instead the function
line_first_intersection_point_with is used.

I have only kept in an include directory at the root
the change in arrangement point location.
This change also requires to use some special local
includes in CMakeLists.txt files. I will do it in a
subsequent commit.
