Hi there,
I have started using Logstash just recently. How do I make use of Extractnumbers plugin with Logstash ?
I can find its usage with options but don't seem to find the simplest example of a basic use case of extracting numbers from a string.

It's just pattern matching. Here is an example
```
input { generator { count => 1 lines => ['12 10.1 foo 5 10.2 10'] } }
filter { extractnumbers {} }
output { stdout { codec => rubydebug { metadata => false } } }
```
produces
```
"int3" => 10,
"float2" => 10.2,
"int2" => 5,
"int1" => 12,
"float1" => 10.1
```
