Added a few things and finished cleaning up changes to INSTALL
ExamMeta.PatientID type changed to int

From tinyint.  Not sure what went through my head but tinyint is clearly not big enough.
Update updateExam.php

Added additional comments which (1) helps keep connection alive, and (2) breaks up update into 7 chunks of 1-day updates rather than a single 7-day update, which also helps keep connection to RIS alive.

Added comment explaining how to start culling of RIS data from an arbitrary date.
