/**
 * Made this class fully public for next extend cases
 * For now it's unclear is this need to split FileContent class to different ones
 *
 * F.e. ParsedFile could have two methods returning SimpleContent and UnicodeFreeContent 
 * And each *Content class could have unique logic in it
 * 
 * ParsedFile is thread safe because of immutability
