moved the "Dimension" class to the DropCutter to avoid circular imports under some circumstances (thanks to Dan Heeks)

hide the previous toolpaths after generating a new one, if there was only one visible before (this should be less confusing)
display the number of current toolpaths in the toolpath tab label

git-svn-id: https://pycam.svn.sourceforge.net/svnroot/pycam/trunk@178 bbaffbd6-741e-11dd-a85d-61de82d9cad9

 * export multiple toolpaths to a single gcode file
 * sort toolpaths arbitrarily
 * deleted a toolpath from the list

git-svn-id: https://pycam.svn.sourceforge.net/svnroot/pycam/trunk@176 bbaffbd6-741e-11dd-a85d-61de82d9cad9

 * tool-id (e.g. "T1")
 * allow to use general IO streams instead of a file output
 * allow to skip the "M2" command ("end program") for multiple assembled toolpaths


git-svn-id: https://pycam.svn.sourceforge.net/svnroot/pycam/trunk@175 bbaffbd6-741e-11dd-a85d-61de82d9cad9

added basic support for multiple toolpaths

tool id written by the gcode exporter is configurable (not used for now)

 - pycam did not start on Windows
 - PyODE occasionally exposed a threading bug ("Exception exceptions.KeyError: (...,) in 'ode.collide_callback' ignored") preventing ODE from detecting any collisions
  - this rarely happened with the "Finish" processing template
  - this usually happened with the "Rough" processing template
Thus the threading code is gone again. Instead there will be lazy GUI updates via gtk.main_iteration in the draw_callback function.


git-svn-id: https://pycam.svn.sourceforge.net/svnroot/pycam/trunk@171 bbaffbd6-741e-11dd-a85d-61de82d9cad9

added example key handler for 3d window


git-svn-id: https://pycam.svn.sourceforge.net/svnroot/pycam/trunk@170 bbaffbd6-741e-11dd-a85d-61de82d9cad9

closing the main window cancels a potentially running multi-threaded calculation

prevent the DropCutter from going down to zero, if the model exceeds the height of the bounding box (introduced by the new dropcutter code)
 - this (obviously) violates the boundary box limits


git-svn-id: https://pycam.svn.sourceforge.net/svnroot/pycam/trunk@166 bbaffbd6-741e-11dd-a85d-61de82d9cad9

changed the gcode exporter code to allow a specific definition of the safety height (instead of previous "max(safetyheight, homeheight, startz)")
moved "startz" offset (based on the configured measurement unit) from SimpleGCodeExporter to the Gui code to allow more control
slight beautification of the gcode exporter code (added spaces between operators and after commas - according to PEP 8)
