updating logging level for agent class to INFO
adding trackUniqueClients parameter to specify if stats should be captured for all clients...or if avaerage of all clients is enough (which is the default)
fixed bug with metric minimum value: Float.MIN_VALUE is not the min possible value...-Float.MAX_VALUE is!
added capability to track stats accross all clients and average it by default. extra option to also capture the stats for each clients as well.
