Let's say you have an iOS project, and you want to use some external library, like AFNetworking. How do you integrate it?

With submodules

Add the project to your repo:

git submodule add git@github.com:AFNetworking/AFNetworking.git Vendor/AFNetworking

or something to that effect.

# Public: A module to be mixed in another class with common methods to index
# records in ElasticSearch.
#
# The host object needs to respond to 'indexed_attributes', which will return
# an array of the attributes names to be indexed.
#
# It's also recommended to override the 'save?' method to make sure only
# records that match some specifications are indexed.
#
# The type used for the ElasticSearch index will be extracted from the name of
