Routines to handle family data with a pedigree object. The
initial purpose was to create correlation structures that
describe family relationships such as kinship and
identity-by-descent, which can be used to model family data in
mixed effects models, such as in the coxme function.  Also
includes a tool for pedigree drawing which is focused on
producing compact layouts without intervention.  Recent
additions include utilities to trim the pedigree object with
various criteria.
