Created a more generic cohort definition for the cross-site indicator report
that allows for CD4 counts with an HIV OR lab encounter. Updated xsite Q9 to
include this more generic cohort (allowing CD4 counts from lab encounters).
Removed the requirement that CD4 counts be related to an encounter type by removing this requirement
in the getPatientsWithAnyObsWithinMonthsByEndDate method. Updated the HIV Indicators Report and the
Cross-site indicators report accordingly.
