Update of /cvsroot/bprocessor/model/src/net/sourceforge/bprocessor/model
In directory sc8-pr-cvs3.sourceforge.net:/tmp/cvs-serv12986/src/net/sourceforge/bprocessor/model
Modified Files:
CoordinateSystem.java
Log Message:
Added constructor method that make a default coordinatesystem around a given origin (usefull for default feedback constructors) and added a method the gives the to or three edges of the coordinatesystem (i,j when only plane and i,j,n otherwise) as Guide objects just as in Line, used when drawing selection
