Fix pathing in examples

I'm looking to use this gem for a project; upon reading that the examples are really the only true documentation and finding that most of them don't actually work by installing the gem and running them, I went through and fixed the pathing so they would run and I could see how they look. (Large diff is from being a lazy pedant with auto removing whitespace). 

Some dull contributions but I figured you might want them from my fork anyway. Neat project.
