Enum: PrevalenceMeasureEnum

The kind of epidemiological measure a Prevalence record reports. Disease occurrence is reported in several non-interchangeable ways; this enum makes the measure explicit so a point prevalence is never silently compared with an incidence rate or a literature case-count. Mirrors the "type" column of the Orphanet epidemiology table.
