Basic Family Use Case

The most basic functionality as it applies to a family includes:

• Create a pedigree chart
• Get the family group sheet data for an individual

Basic assumptions

• A parent can have 0 or more children
• A child can have 0 or more Parents. The :order attribute determines which is the father (0) and mother (1). Other values are supported but have no semantic meaning.
• All edges will have a :preferred flag that will indicate the default path through the graph.

Use Case 1: Pedigree Chart

A pedigree chart requires an Individual iand returns a seq of Individuals. The first element is the "father" and the second is the mother. If either of them is not known, a nil will be in that place. If more elements are returned, they are ignored.

The gremlin query will be something like: g.v(i).inE('child').outV('birth').outE('parent')
