/*
* Initialize new Timer
*
* @since 1.2.0
*
* The timers could used to trigger reccuring events or implement timeouts.
* The library will call given block after time interval pass.
*
* @param bucket [Bucket] the connection object
* @param interval [Fixnum] the interval in microseconds
* @param options [Hash]
* @option options [Boolean] :periodic (false) set it to +true+ if the timer
* should be triggered until it will be canceled.
*
* @yieldparam [Timer] timer the current timer
*
* @example Create regular timer for 0.5 second
* c.run do
* Couchbase::Timer.new(c, 500000) do
* puts "ding-dong"
* end
* end
*
* @example Create periodic timer
* n = 10
* c.run do
* Couchbase::Timer.new(c, 500000, :periodic => true) do |tm|
* puts "#{n}"
* n -= 1
* tm.cancel if n.zero?
* end
* end
*
*
* @return [Couchbase::Timer]
