-Description: A few functions aim to provide a statistic tool for three purposes. First, simulate kin pairs data based on the assumption that every trait is affected by genetic effects (A), common environmental effects (C) and unique environmental effects (E). Second, use kin pairs data to fit an ACE model and get model fit output. Third, calculate power of A estimate given a specific condition. For the mechanisms of power calculation, we suggest to check Visscher(2004) <doi:10.1375/twin.7.5.505>.

 The goal of ACEsimFit is 1) to simulate kin pairs data based on the
 theory of ACE models. 2) to fit data with ACE models
