Gets person year (PY) contributions to a particular time since diagnosis (tsd) interval from survival times.
getPY(surv, bin, binS, brks)The total survival time of the patient.
The label of the specific bin of interest.
The character vector of bin labels in which binLab exists.
The numeric vector of break points used by cut to create binS.
A vector as long as the survival vector input of PY at risk in a particular interval.

getPY(survTimes,binS[1],binS,brks)# all contribute 0.25 to first interval
