/**
|

* PlaylistLoader - delegate for media manifest/playlist loading tasks. Takes care of parsing media to internal data-models.
|
||||
*
|
||||
* Once loaded, dispatches events with parsed data-models of manifest/levels/audio/subtitle tracks.
|
||||
*
|
||||
* Uses loader(s) set in config to do actual internal loading of resource tasks.
