Upgraded the package to Julia 1.0 and dropped support for older versions.
Some function names have changed to reflect the names of LinearAlgebra.jl better:
reig -> reigen
rsvdfact -> rsvd
idfact -> id
svdfact_restricted -> svd_restricted
svdfact_re -> svd_re
eigfact_restricted -> eigen_restricted
eigfact_re -> eigen_re
eigfact_nystrom -> eigen_nystrom
eigfact_onepass -> eigen_onepass
