1.1: corrected C++ code (compilation errors on some distributions)
1.2: kinhsip matrix is now in single precision (faster) 
     various minor changes
1.3: corrected bug in HWE chi square (monomorphic SNP) 
     select.snps and select.inds (negative indices, presence of NAs)
1.3.1: suppressed various __attribute__ ((aligned(16))) in m4_kinship*.cpp
       which seemed to be causing an (intermittent) bug (?!)
1.4: introduced option gastion.auto.set.stats / updated vignette accordingly
     +hz in ped stats
     new function reshape.GRM
     as.bed.matrix no longer is a method, but a function
     minor modifs in read.vcf
     matrix4 now uses uint8_t array instead of char array (induced many 
     small changes in the C++ code).
1.4.5: corrected a bug in method 'show'
       better handling of constraints in AIREML methods 
       faster implementation of GRM
       new function of genomic.sex
1.4.6: Modified Imports/Depends fields to remove a warning about RcppParallel
       Modified VCF handling functions to follow the new interface of WhopGenome 
       (patch by Tomas Kalibebera and Ulrich Wittelsbuerger)
       New functions logistic.mm.aireml, score.variance.linear, score.variance.logistic, score.fixed.linear, score.fixed.logistic
       New argument get.P in lmm.aireml
       New features and arguments in association.test
       Minor modifications of the vignette (illustration of association.test)
