compilation Phase III introduces multiplicate statements

[ncatlett]

Edges introduced in Phase III (family membership, named complex components, transcribedTo, translatedTo, orthologous) are backed by multiple (as many as 6 or 7) identical statements from the resource documents.

[ncatlett]

Expected behavior -
Statements should be considered identical (and collapse) if they have the same:
source term label
target term label
relationship
document (as identified by document name and version)
annotations (citation, evidence, tissue, etc.)
