Carry out principal component analysis (PCA) of very large pedigrees such as found
in breeding populations! This package, 'randPedPCA', exploits sparse matrices and randomised
linear algebra to deliver a gazillion-times speed-up compared to naive singular value decoposition (SVD)
(and eigen decomposition).
