Doesn't work with ruby 2.3

[pocke]

Hi. I use https://github.com/berkshelf/ridley . and I encounter many errors with ruby 2.3 .

Hash#dig is defined in ruby 2.3.
However, buff-extensions also defines dig method.

• https://www.ruby-lang.org/en/news/2015/12/25/ruby-2-3-0-released/
• https://github.com/reset/buff-extensions/blob/master/lib/buff/extensions/hash/dotted_paths.rb#L87

These are in conflict. So, I encounter many errors in ridley.

Hash#dig should be renamed.
But the above is breaking change...
What do you think ?

Buff::Extensions::Hash::DottedPaths
  ClassMethods
    ::from_dotted_path
      returns a new Hash
      returns a hash containing the nested keys
      sets a nil value for the deepest nested item
      handles a symbol as the dotted path
      when given a seed value
        sets the value of the deepest nested item to the seed
  #dig
    returns nil if given a blank string
    returns 'false' nested values as 'false' and not 'nil' (FAILED - 1)
    when the Hash contains the nested path
      returns the value at the dotted path (FAILED - 2)
    when the Hash does not contain the nested path
      returns a nil value
    when the Hash contains symbols for keys
      returns the value at the dotted path (FAILED - 3)
  #dotted_paths
    returns an array
    given a hash with only top level keys
      returns an array of the top level keys as strings
    given a hash with empty hashes as values
      returns an array of the top level keys as strings
    given a hash with nested keys
      returns an array of dotted paths including the nested Hash keys
