72006fe05b Added custom multiprocessing module: 
- allows starting new processes and controlling them remotely from the parent process
  - remote processes can run their own GUI, Qt signals can be connected between processes
    (in general this is not possible with the built-in multiprocessing module due to
    the use of fork() ).
  - Control works by a system of proxy-objects such that controlling a remote process
    looks almost exactly like working with local objects.
  - Uses sockets to communicate between processes (so in theory could be made to 
    work over a network), but also includes a mode that uses fork() to allow fast
    parallelization.
  - Wicked-easy inline parallelization by adding only one line of code to break up work between
    processes (requires fork; sorry windows users)

c7a78642fd Added interactive console widget: 
- GUI interactive python prompt, useful in a variety of situations where
    python -i or ipython don't work very well. 
  - Command history (requires a little help finding storage for this)
  - Exception catching, allowing the user to inspect local variables 
    at any level within a stack trace (currently, this is done _without_
    blocking the application)

364337083f Added workaround for Qt crash-at-exit bug (make sure that all GraphicsItems live in a scene before exiting) 2012-06-18 14:01:51 -04:00

6932c34126 - Added workaround for Qt bug: https://bugreports.qt-project.org/browse/QTBUG-18616. (GraphicsItem.setParent needs to check for scene change first) 
This _could_ cause other problems, but they will certainly be fewer than the existing problems.

- Fixed bugs with ViewBox linking to views which are subsequently deleted
