dot_hash's Issues

README suggestions

Would be useful to mention any reasons why someone should consider using this gem over alternatives like OpenStruct (which is in the standard library so it's usually someone's goto). For example, OpenStruct cannot handle nested hashes properly, while this gem can. I didn't know that until trying to find a reason why I would want to use this gem.

Another suggestion is to indicate in an example what happens when a key isn't found. Does it return nil or does it raise like #fetch does? If it returns nil by default, can it be configured to raise?

NoMethodError for Hash

If you have an "empty" value in a Yaml file an unfriendly error is thrown:

dog:
  bark:
  bite: "hard"

Settings.dog.bite #=> "hard"
Settings.dog.bark
#=>
NoMethodError: undefined method `bark' for #<Hash:0x007f694ee97de8>
from /home/marsalis/.rbenv/versions/2.1.1/lib/ruby/gems/2.1.0/gems/dot_hash-0.5.5/lib/dot_hash/properties.rb:45:in `public_send'

I am not sure what the best solution is here. We could 1) set empty values to nil, or 2) raise a better error message. The error message happens on Hash not the object itself. This might make it difficult to find the source of the error. In the example, there is only one bark method. But, if the setting was more generic, like username or test_mode, it would be harder to trace the error.
