fix imports for CRAN

[jefferis]

We should submit a version to CRAN to accompany the paper. v 1.5 is coming up with errors on r-devel due to stricter namespace checking. These buglets still exsist.

to your NAMESPACE file.

I think this is fixed as of f4d9eb2d016ab731b65836343e408c0acc73267b, but I'm having trouble installing all the packages to check on my machine with R-devel, as igraph and RcppEigen aren't happy on the Fortran front.

Thanks @ajdm. I just triggered a winbuilder build (devtools::build_win) which should confirm. You'll get the email!

[jefferis]

@ajdm was winbuilder happy with latest build?

[jdmanton]

Yes, but CRAN was not. I need to fix the VignetteIndex and then they should be happy.

[jefferis]

Thanks! I actually have one minor enhancement to push later tonight. Best, Greg.

Brilliant! Thanks!
