Use background process for Statistics calculation.

[GabeStah]

Create Statistic model to house all appropriate data.

• type:string - Class type for record (e.g. Standing)
• record_id:integer - Id of record
• key_name:variety - formatted, ordered key to retrieve value. Created through method to combine terms alphabetically. All keys should have separate column for simplicity and best practices:

def key(*args)
  all = args.map { |arg| arg.to_s.downcase }
  all.sort if all
  all.join('_')
end

Outputs:

>> Standing.key(:raids, :absent, :total)
"absent_raids_total"
