class  GccEnt
 This package provides an implementation of the qualified
entities useful to create 2d entities with geometric
constraints. The qualifier explains which subfamily of
solutions we want to obtain. It uses the following law: the
matter/the interior side is at the left of the line, if we go
from the beginning to the end.
The qualifiers are:
Enclosing : the solution(s) must enclose the argument.
Enclosed : the solution(s) must be enclosed in the
argument.
Outside : both the solution(s) and the argument must be
outside to each other.
Unqualified : the position is undefined, so give all the
solutions.
The use of a qualifier is always required if such
subfamilies exist. For example, it is not used for a point.
Note: the interior of a curve is defined as the left-hand
side of the curve in relation to its orientation.
