fixed spelling error in last change
default startDataRow to 2
startDataRow is required (and has a default, so no biggie)
import pageTitle mod
couple mods to get methods that were throwing NullPointerException when
import PropertyUtils.describe invoked them, because they had never been
called in a situation where certain properties could be null, as is the
case with import when new entities are being created
was erroneously trying to retrieve Patient in case where Patient already
exists

support in setProperty for ignoring case when matching mapping property
name to real property name to make it easier on coordinators creating
import definitions and mapping files

improved messaging to include patient id if patient exists, format dates

fixed up code and message around instrument created and already existing
