Walky - Simple lib to walky through easily hashes

Walky try create a simple way to access hashes with many keys easily. You can move through hashes and also access others hashes with the same path

Example:

@hash = { "menu" => { 
  "header"   => {
    "screen" => "LCD", 
    "meme"   => "Like a boss"
  }
}

If we have an hash like above, you can use Walky like this:

@walky = Walky::Walker.new(@hash)

@walky["menu header screen"]      # => "LCD"
# Or:
@walky.walk("menu header screen") # => "LCD" 

If you want to access multiple hashes that have the same keys that the first, you can use Walky#same_path. Example using with the code above:

@other    = { "menu" => { "header" => { "screen" => "LED"  , "meme" => "Poker face" } } }
@more_one = { "menu" => { "header" => { "screen" => "PLASM", "meme" => "LOL"        } } }

# Acessing multiple hashes with one hash key
@walky["menu header"].same_path(@other, @more_one).all do |a, b, c|
  a["screen"] # => "LCD"
  b["screen"] # => "LED"
  c["screen"] # => "PLASM"
end
