git-merge-structure-sql: No such file or directory @ rb_sysopen - /Users/X/.gitattributes

Thanks for the work on this, looks great!

When I was running git-merge-structure-sql --install, I got the error:

git-merge-structure-sql: No such file or directory @ rb_sysopen - /Users/X/.gitattributes

I'm not entirely sure how .gitattributes normally gets initialized, but I was wondering how you generally approach this. We want to have this initialized easily for our engineering team, so not doing this manually would be ideal. Additionally, we are running this directly from a rails codebase and have a .gitattributes file checked in, but based on the locations searches, it won't use it. So, we see 2 options:

1. Find a way to initialize .gitattributes, not sure if it makes sense to be in this library
2. Support looking for .gitattributes in the current directory we are installing git-merge-structure-sql in

Maybe we are approaching this wrong and there's another approach that would work, suggestions welcome!
