Prevent uploading of big files to UsageData

[Anders Markvardsen]

Create a git hook, similar to that for AutoTestData, that discourage uploading of large files to ​https://github.com/mantidproject/usagedata

Russell points out:

The code for limiting the file size in the main repo is at ​https://github.com/mantidproject/mantid/blob/master/.githooks/pre-commit#L144. The thing is though that in order for this hook to fire, the file needs end up in the .git/hooks/ directory, which only exists in a cloned repo, not on github. We solve this problem by having CMake silently copy it into the right place. That option is of course not available for your repo so I think you may be stuck. I'm not sure there's anything better you can do than shout it loudly in the README. I suppose you could add the file and ask people to manually copy it into the right place (but they won't). Alternatively, you could look at other storage solutions (Dropbox like) as these files don't need versioning. I don't know if there's anything where you can limit file size though.
