     # == SFS 1.1 Description
-    # 
+    #
     # A MultiCurve is a 1-dimensional GeometryCollection whose elements are
     # Curves.
-    # 
+    #
     # MultiCurve is a non-instantiable class in this specification; it
     # defines a set of methods for its subclasses and is included for
     # reasons of extensibility.
-    # 
+    #
     # A MultiCurve is simple if and only if all of its elements are simple
     # and the only intersections between any two elements occur at Points
     # that are on the boundaries of both elements.
-    # 
+    #
     # The boundary of a MultiCurve is obtained by applying the "mod 2"
     # union rule: A Point is in the boundary of a MultiCurve if it is in
     # the boundaries of an odd number of elements of the MultiCurve.
-    # 
+    #
     # A MultiCurve is closed if all of its elements are closed. The
     # boundary of a closed MultiCurve is always empty.
-    # 
+    #
     # A MultiCurve is defined as topologically closed.
-    # 
+    #
     # == Notes
-    # 
+    #
     # MultiCurve is defined as a module and is provided primarily
     # for the sake of documentation. Implementations need not necessarily
     # include this module itself. Therefore, you should not depend on the
     # kind_of? method to check type. Instead, use the provided check_type
     # class method (or === operator) defined in the Type module.
