epi.calc: Effective probability of infection (EPI)
In evansergeant/RSurveillance: Design and Analysis of Disease Surveillance Activities

Calculates effective probability of infection (adjusted design prevalence) for each risk group for risk-based surveillance activities

1	epi.calc(pstar, rr, ppr)

`pstar`	design prevalence (scalar)
`rr`	relative risk values (vector of values corresponding to the number of risk strata)
`ppr`	population proportions corresponding to rr values (vector of equal length to rr)

list of 2 elements, a vector of EPI values and a vector of corresponding adjusted risks (in corresponding order to rr)
