A data.frame is returned
prior number of control events
prior number of treatment events
prior estimate for HR
randomization ratio
Interim HR
Interim events
final events
TPP Target Value aka Base TPP
TPP Lower Reference Value aka Max TPP (large HRs lead to No-Go)
threshold associated with Base TPP
threshold associated with Min TPP
threshold associated with No-Go
HR needed for ng; leave null for standard rule
HR needed for go; leave null for standard rule
go threshold for predictive probability
no-go threshold for predictive probability
