# The QueryAssociationSplitter takes in a query and removes any .includes, and
# returns the new query, and an hash of association parts.
#
# Example:
# QueryAssociationSplitter.split([['where', {name: 'Bob'}], ['includes', [:posts, [:posts, :comments], :links]]])
# => ['where', {name: 'Bob'}], {:posts=>{:comments=>{}}, :links=>{}}]
