+/** \class SketchPlugin_Trim
+ * \ingroup Plugins
+ * \brief Feature for creation of a new constraint splitting object. Entities for split:
+ * - Linear segment by point(s) on this line
+ * - Arc by point(s) on this arc
+ * - Circle by at least 2 split-points on this circle
+ *
+ * The following constraints will be applied after split to keep the divided segments geometry:
+ * - Coincident constraints for both parts of created segments in the point of splitting
+ * - For linear segments parallel, for circles - tangent constraint, for arc - tangent and equal
+ * constraints. In case of three segments in result two couple of constraints are created
+ * - parallel and equal constraints: the first is between 1st and middle entity, the second is
+ * between 1st and 3rd.
+ * - tangency constraints: the first between 1st and 2nd, the second between 2nd and 3rd.
+ * - Constraints assigned to the feature before split operation are assigned after using rules:
+ * - Coincident constraints are assigned to the segment where they belong to. Segment of split
+ * has only a coincidence to the neighbor segment. All constraints used in the splitting of
+ * this segment are moved to point of neighbor segment. If constraint was initially built
+ * to the point of splitting segment, it stays for this point.
+ * - Geometrical and dimensional constraints are assigned to one of result segment, not the
+ * selected for split. In case of 3 result segments, this will be the segment nearest to the
+ * start point of arc/line.
+ * - Replication constraint used split feature will be deleted in the same way as it is deleted
+ * by any of entity delete in sketch which is used in this constraint.
+ *
+ * This constraint has three attributes:
+ * SketchPlugin_Constraint::VALUE() contains reference object to be splitted
+ * SketchPlugin_Constraint::ENTITY_A() and SketchPlugin_Constraint::ENTITY_B() for the points of split;
