I took a few seconds to clean up the SEI drop down menu in the site map. Things I changed:
- Got rid of the link to the Newtonian Noise Area overview screen (the L4Cs have been removed and returned to original owners, the NGN front-end model is now gone.)
- Got rid of the link to the corner-station compact BRS overview (same with the NGN array, this has been removed both in hardware and software)
- Renamed "COMPACT SEISMON" to just "SEISMON"
- Renamed "ISI CONFIG" to the more descriptive "ISI SENSOCR CONFIG"
- Renamed "IFO Basis SUSPOINT Motion" to "IFO BASIS PROJECTIONS"
- Renamed "PERF OVERVIEW" to "PERFORMANCE MATRICES"
- Re-ordered the list in order of frequency of use

These changes have been committed to the userapps repo under
    /opt/rtcds/userapps/release/cds/h1/medm/SITEMAP.adl

Attached are screenshots of the menu AFTER and BEFORE.
