Logstash split field solution.

	Problem: We have a log line that includes a perl class that we want to log the class
	and method in their respected fields. An example class and method in perl:

	Animal::Dog::bark

	In this example, "bark" is the method. "Animal::Dog" is the class.

	After some searching and hacking, I found a solution that works with Logstash 1.4.2

	Assume the input is "Animal::Dog::bark".
