\description{
Simulation of recurrent events data based on cumulative hazards
}
\details{
Must give hazard of death and two recurrent events.  Possible with two
event types and their dependence can be specified but the two recurrent events need
to share random effect. Based on drawing the from cumhaz and cumhaz2 and 
taking the first event rather
the cumulative and then distributing it out. Key advantage of this is that 
there is  more flexibility wrt random effects

## getting some rates to mimick

data(base1cumhaz)

base1 <- base1cumhaz
base4 <- base4cumhaz

### simulating simple model that mimicks data 
### now with two event types and second type has same rate as death rate
