/*
* Jmol 12 implementation of the Molecular Playground
*
* includes message "banner:xxxxx" intercept to
* display xxxxx on the banner, thus allowing that to
* be modified by a running script. (in JsonNioService.java)
version=12.3.3_dev
# new feature: MolecularPlayground now accepts messages to the banner:
# message banner: xxxxxxx
# new feature: MolecularPlayground fully functional.
# This application (MPJmolApp) is part of a three-part suite
# that runs on a Mac mini involving:
# "Hub" [name] for overall control (Mac app; not open source yet)
# MPKinectDriver for obtaining motion events (Mac app; not open source yet)
# MPJmolApp for displaying the results (source here)
# The Hub and MPJmolApp communicate over local port 31416, sending
# JSON messages back and forth. (See note in org.jmol.app.jsonkiosk.JsonNioService.java)
# For demonstrations of the installation at St. Olaf College,
# see the following YouTube videos:
# http://www.youtube.com/watch?v=iQRkuku8ry0
# http://www.youtube.com/watch?v=XCRrRZe1j6g
# http://www.youtube.com/watch?v=FTTIVWGtFD0
# For details relating to the original Molecular Playground
# installation at U. Mass.-Amherst, see
# http://molecularPlayground.org
# Note that all of the functionality of the original MP are
# present in MPJmolApp
# new feature: MolecularPLayground can now ignore all Hub requests for
# commands and content changes, thus allowing its own configuration
# script to drive the presentation instead of the Hub's. So the Hub
# can be used simply as an interface to the Kinect driver. This just
# allows a simpler development interface -- a simple three-column Excel file can
# be used to drive a presentation. (see org.jmol.molecularplayground.biophysics.xlsx)
# -- MPJmolApp looks for the file MpJmolAppConfig.spt
# -- This file can override MPJmolApp's default parameters:
# NIOContentPath
# -- default: System.getProperty("user.dir").replace('\\', '/')
# + "/Content-Cache/%ID%/%ID%.json"
# -- ignored if NIOcontentDisabled ends up true (see below)
# NIOterminatorMessage
# -- default: "MP_DONE"
# NIOresetMessage
# -- default: "MP_RESET"
# NIObannerEnabled
# -- default: true
# NIOcontentScript
# -- default: (not present, setting NIOcontentDisabled=false)
# NIOcontentDisabled
# -- default: true if NIOcontentScript is present; false if not
# NIOmotionDisabled
# -- default: false
# -- The script in MpJmolAppConfig.spt is run, along with whatever
# default settings are generated by the above checks.
# -- Parameters are set by querying the Viewer for those Jmol variables.
# -- If NIOcontentDisabled is true, then all JSON messages from the Hub
# of types "content", "command", and "banner" are ignored. It is still
# important that the running script send "MP_DONE" messages periodically
# (within every 6 minutes) so that the Hub knows that MPJmolApp is still
# alive and does not try to restart it.
# -- If NIOmotionDisabled is true, then all JSON messages from the Hub
# of types "move", "sync", and "touch" are ignored.
# -- These are checked every time a JSON command is received, so the
# running script can specifically turn off motion detection if that
# or content detection if that is desired.
# -- Note that MPJmolApp has a full console and menu that are available
# on the operator's screen, (which is just mirrored to the projector).
# This allows for parameter setting and adjustments on the fly.
