#StimGen python
# StimGen is a Qt-based python application for designing and presenting visual stimuli through a projector
# or other external monitor. The interface is an arrangement of Qt widgets that set stimulus parameters such
# as the type of object, and its size, orientation, motion, timing, etc. These parameters are all imported into a master
# stimulus dictionary called 'stim', which is then recalled at runtime. Stimuli are generally produced frame-by-frame as
# they are presented, except for some cases where the entire stimulus is held in memory before-hand. Stimuli are
# saved into a stimulus bank on disk, and is able to be recalled in future sessions.
