---Purpose: Template class for the intersection algorithm required

-- by the 3D classifications.
|
|
--
|
|
-- (a intersection point near the origin of the line, ie.
|
|
-- at a distance less or equal than <tolerance>, will be
|
|
-- returned even if it has a negative parameter.)

-- Only the point with the smallest parameter on the

|
|
-- The Tolerance <Tol> is used to determine if the

|
|
-- that case, the parameter of the intersection point
|
|
-- on the line can be a negative value (greater than -Tol).
