Sample selection function for selecting representative samples of a target population

1 2	sampleSelect(cp, cand, target, nchoose, herit = 0.5, ntry = 300, nrep = 30)

`cp`	a relationship matrx
`cand`	is a vector of indices pointing to the candidates for the sample
`target`	is a vector of indices pointing to the target population
`nchoose`	is the desired sample size
`herit`	is the heritability of the trait
`ntry`	is the number of iterations of the exchange algorithm
`nrep`	is the number of repitions of the exchange algorithm
