Fixes name collision between hclust.jl and HClust.jl in OSX checkout process

[slundberg]

hclust.jl overwrites HClust.jl when doing a package install on OSX. This fixes that by renaming hclust.jl to hclust_impl.jl and allows the package to work on OSX.

See this rant, to which I wholeheartedly agree. This policy recently costed me a day reinstalling a new mac, and caused me to lose backup history on two independent backups.

BTW I have a pull request to include this in Clustering, but it seems kind-of dead. No clue what will happen to it.

I agree a case insensitive FS is a mistake for OSX. As for the pull request, you have this code as GPLv2 and Clustering is under MIT, it might make sense to have this at MIT as well to allows things to be merged.

BTW. Nice package. I was glad to find a pure Julia version of hierarchical clustering so I could share code using clustering without requiring R or Python integration installed.

I submitted a PR to a MIT package so I assume that the code in the PR
automatically becomes MIT licensed.

Makes sense, given you are the sole author.

If you want to run the code under MIT, maybe you can pressure the Clustering.jl maintainers to merge the the PR... Then at least GPLv2 is good for something...
