Statistics

Hi, thanks for great package
i suggest adding errors statistics contain all logs per logs files counts filtered by log entry type like next:
error: 10
info: 3
warring: 5
total errors: 18
i see that in code there is loop over folders and files inside each folder, may be using the same loop and adding read file method to filter the errors can do what i suggested.

• also the statistic my be included in cards above the log viewer container
  i hope this to be good suggestion.
