Tracking which JMeterThread, ThreadGroup produced a sample

[Nathan Chandler]

Think it would be useful if reporters could provide info. on which thread produced a 
sample, e.g. so File Reporter output may look like:

# Sample data created by ###

# JMeterThread    ThreadGroup    Url    Milliseconds

JMThreadXXX    test1    http://blah.com/aaa?page=bbb    176
JMThreadYYY    test1    http://blah.com/aaa?page=bbb    196
JMThreadXXX    test1    http://blah.com/aaa?page=ccc    111
JMThreadYYY    test1    http://blah.com/aaa?page=ccc    165

Others think this useful? Is capture of such information addressed at moment?
