Goal: Produce site overview screen which:
  - has very high information density
  - provides "at a glance" ~real time comprehensive overview of a LIGO detector
  - covers alarms, medm, veto, diagnostic information and short performance history
  - intended for somewhat experienced people (no static info is displayed)
  - act as a link center for web pages used for toubleshoting
  - web browser readable but fully graphical with NO scrolling required on modern displays

The first version will contain:

 - Each graph or number displayed
  - has an absolute minimum of static info displayed to inrease density
    (no labels, scales, etc.)
  - has pop up information to help interpretation (for the novice)
    (scales, synopsis, etc.)
  - has a hyperlink to provide the correct plot and explanation for the specific entity

 - 4 sidebars (upper, lower, left and right)
  - Left sidebar:
   - DMT monitor alarm indicators with links to detailed alarm pages
   - DAQ, LDAS alarms and links to up to date medm screenshots
  - Right sidebar:
   - interferometer status lights, info with links to relavant plots and screenshots
  - Top bar
   - descriptive numbers provided by DMT monitors (trigger density, veto rate, timing, etc.)
  - Bottom bar
   - moving banner containing less crucial but valuable information
     (runs twice between each refresh of the page)

 - Core region (Upper core and Lower core)
  - Upper core:
   - Contains narrow and lond strip charts: (Identical time axis)
    - spectrogram (whitened, processed, logarithmic time scale (TBD))
    - band limited (LIGO band) RMS of AS_Q with marked vetoed regions
    - environmental strip chart (blrms of seismic channels)
    - time evolution of cruicial narrow bands of AS_Q (blrms)
    - astrophysical reach and coincident lock statistics (color coded strip)
  - Lower core:
    - Contains four rectangular graphs:
     - Calibrated spectra
      - processed AS_Q
      - composite high and low noise models (max and min for each bin for a given time)
      - acceptable region with (start tuningand stop tuning limits)
     - Lock strech and duty cycle history for multiple ifos
     - Histograms
     - TBD

It is assumed that the display can handle 1280x1024 pixel resolution.
Nominal refresh rate is ~2 minutes. Most graphs and numbers rely on
existing (or soon to be) monitors, channels.
