Initial stab at HMM for calc_genoprob
Fix two small HMM bugs; add test of calc_genoprob for backcross
Add test of calc_genoprob in intercross
test calc_genoprob for riself/risib (using hyper data)
Small changes to includes in c++ files
class Cross -> class QTLCross (to avoid confusion with Eigen::Cross)
cross_f2pk: nrec should really be proportion recombinants
debug_util: specify Eigen::
trying to get est_map to work
have est_map working; tricky bit was need to omit individuals with <2 genotypes
Revise data + version; re-add Travis CI
