Makes crosses within a population using a user supplied crossing plan.
Value
Returns an object of Pop-class
Examples
#Create founder haplotypes
founderPop = quickHaplo(nInd=10, nChr=1, segSites=10)
#Set simulation parameters
SP = SimParam$new(founderPop)
#Create population
pop = newPop(founderPop, simParam=SP)
#Cross individual 1 with individual 10
crossPlan = matrix(c(1,10), nrow=1, ncol=2)
pop2 = makeCross(pop, crossPlan, simParam=SP)
