class Fluent::MultiEventStream

stream.add(time, record)
2. add events<br>streams ||= MultiEventStream.new
1. initialize blank stream:
Use this class as below, in loop of data-enumeration:
because this class generate less objects than ArrayEventStream.
This class can handle many events more efficiently than ArrayEventStream
EventStream from entries: numbers of pairs of time and record.
