0.5.3.with.linux.binary

[aaronmcdaid]

[The Mac binary isn't in this, but otherwise I think this is ready to go]

This includes:

• A fix for issue #88 . Now we reimpute until at least 100 tags have been reimputed
• If --impute.range or --tag.range are specified, then we can save memory and time by only loading a subset of the build database. For now, we simply load the subset of chromosomes that are referenced in --impute.range/impute.tag
• print the version number as the first line of input. This will be useful when we get reports from users, as we will be able to see exactly which version they are using. (Also, I had to adjust the test system slightly to ensure this printout is ignored in the tests.)

The linux static binary is included in this, and the tests all pass. So the only remaining tasks, as usual with any release, are to add the Mac binary and to do the git tag thing

I am home now, but will

• compile the osx version tomorrow on my other (better) mac
• update the links in the README
• apply the tag magic with git pull master && git tag v0.5.3 master && git push --tags
