Frontpage README documents exists() with optional paths arg. This is not correct.

[kebwi]

The README demonstrates usage of the exists() function with no argument specified. However, the definition for the function clearly doesn't specify an optional value for the paths arg, and attempts to use it as shown in the READMe fail correspondingly.

Hi Keith!

I reviewed the documentation and it was correct.

However, it was easy to miss that cf.exists() applied to CloudFile and not CloudFiles (plural). I increased the typography and clarity of the comment above. I am not sure that will fix it for people that are skimming, but hopefully it will be an improvement.

Let me know if you think I should change it more.
