(Re) Started work on yaml_data/collabda library
Loads yaml data from file
YamlData reload spawns new instances
Sets instance variables from yaml attributes
Yaml data spec cleanup
YamlData implements enumerable
Verified YamlData works with attr_reader
YamlData throws errors if missing source or attributes
YamlData models can be build from an attributes hash
YamlData tracks models so it can reload them
YamlData actually reloads from the file instead of data cache
YamlData checks for file change before each request and reloads
Student blogs use YamlData and are auto sorted.
Started moving YamlData towards more general collabda idea.
Renamed YamlData model reload to build_collection
Added Json source type.
Added collection builder to YamlData/Collabda
Renamed YamlData files to Collabda
Renamed YamlData to Collabda
