DeleteSection would be really useful

[Nick Craig-Wood]

DeleteSection would be really useful - it isn't possible at the moment. Deleting all the keys still leaves the section behind.

Thanks for a very useful package

I also added a test case for the API, which is almost same you gave in #9 but for sections

Thanks for doing this - very useful in my current project :-)

No problem!
