Creates a function that aggregates a collection, creating an object or
array composed from the results of running each element of the collection
through a callback. The given `setter` function sets the keys and values
of the composed object or array.

@private
@param {Function} setter The setter function.
@param {boolean} [retArray=false] A flag to indicate that the aggregator
function should return an array.
@returns {Function} Returns the new aggregator function.
Creates a function that aggregates a collection creating an object or array composed from the results of running each element of the collection through a callback . The given setter function sets the keys and values of the composed object or array .
