// Description: The Segments class is the base class for
|
|
// both the normal segments and the connectors. The main difference
|
|
// between a segment and a connector is, that a connector only provide
|
|
// equations. A normal segment contains both. All
|
|
// common stuff, such as a name, initialization
|
|
