to_collection 1.0.0

Treat an array of objects and a singular object uniformly as a collection of objects. Especially useful in processing REST Web Service API JSON responses in a functional approach. Canonicalize data to treat uniformly whether it comes in as a single object or an array of objects, dropping `nils` out automatically. API: `object.to_collection(compact)` where `compact` is a boolean for whether to compact collection or not. It is true by default. Example: ```ruby city_counts = {} people_http_request.to_collection.each do |person| city_counts[person["city"]] ||= 0 city_counts[person["city"]] += 1 end ``` Wanna keep `nil` values? No problem! Just pass `false` as an argument: ```ruby bad_people_count = 0 city_counts = {} people_http_request.to_collection(false).each do |person| if person.nil? bad_people_count += 1 else city_counts[person["city"]] ||= 0 city_counts[person["city"]] += 1 end end ```
