Create the event history matrix needed for the event timing algorithm

1 2	makeEventHistory(type = c("gain", "LOH"), copies = NULL, totalCopy = sum(copies), onlyIdentifiable = TRUE)

`type`
`copies`	a vector of length 2, giving the number of copies of the maternal and paternal chromosomes
`totalCopy`	an integer between 2 and 5. totalCopy must be the sum of the numbers given for the argument copies
`onlyIdentifiable`	logical. Only return event matrices corresponding to event histories with identifiable pi[0]?

The A matrix relates allele frequencies to the event history. The vector A pi gives the probabilities of each allele frequency possible for the specified event.
