``LiveEnhancedPbpLoader`` loads pbp data for a game and creates :obj:`~pbpstats.resources.enhanced_pbp.enhanced_pbp_item.EnhancedPbpItem` objects for each event
Enhanced data for each event includes current players on floor, score, fouls to give and number of fouls committed by each player,
plus additional data depending on event type
The following code will load pbp data for game id "0021900001" from a file located in a subdirectory of the /data directory
