Determine founder genotype at the disease locus and determime their relative-risk of disease

1	sim_founderRVstatus(GRR, carrier_prob, RVfounder)

`GRR`	Numeric. The genetic relative-risk of disease, i.e. the relative-risk of disease for individuals who carry at least one copy of the causal variant. Note: When simulating diseases with multiple subtypes `GRR` must contain one entry for each simulated subtype. See details.
`carrier_prob`	Numeric. The carrier probability for all causal variants with relative-risk of disease `GRR`. By default, `carrier_prob` `= 0.002`
`RVfounder`	Logical. Indicates if all pedigrees segregate the rare, causal variant. By default, `RVfounder = FALSE` See details.
`intro_RV`	Logical. If `intro_RV = TRUE` a founder has introduced a rare, causal variant to the pedigree, otherwise no RV has been introduced to the pedigree.
