Fix Simple Example

[ryanb]

The simple example in the README raises this exception: undefined method map for nil:NilClass (NoMethodError)

The problem seems to be that a :series option is not given to the timeseries_gauge. Here is a working version (taken from doc/minimal_example.rb).

require "fnordmetric"

FnordMetric.namespace :simple do
  timeseries_gauge :unicorns_seen,
    :tick => 30.seconds,
    :calculate => :average,
    :series => [:num_unicorns]

  event :unicorn_seen do
    incr :unicorns_seen, :num_unicorns, rand(5)
  end
end

FnordMetric.standalone
