Compute the three modified Haybittle-Peto boundaries
Usage

2
computeMHPBoundaries(prevalence, N, alpha, beta, eps,
futilityOnly = FALSE)
Arguments
prevalence
the vector of prevalences between 0 and 1 summing
to 1. J, the number of groups, is implicitly the length
of this vector and should be at least 2.
N
a three-vector of total sample size at each stage
alpha
the type I error
beta
the type II error
eps
the fraction (between 0 and 1) of the type 1 error to
spend in the interim stages 1 and 2
futilityOnly
a logical value indicating only the futility
boundary is to be computed; default FALSE
Value
a named vector of three values containing
btilde, b, c
