Allows you to chain methods even if somewhere in the process you start getting nil. This gem uses the nullobject gem so if you get nil, you will get Null::Object.instance instead of nil at the end (which converts nicely to string etc).

Example use (I use a hash as an example since it will return nil if there is no value for a key):

NullChainer.use_nullobject = true # if false, then it will use nil instead of Null::Object.instance
my_hash = Hash.new
NullChain(my_hash)["value"]["value"]["value"].get # => Null::Object.instance

Just remember to call #get after chaining your methods and you’re good to go!

Breaking change: Null::Object.instance not used by default anymore.
