Added skeleton code for worker.
Skeleton for server
Fleshed out server skeleton and a bit of worker skeleton. Need to
implement lauunching mappers, reducers, collecting data, determining
when they're done and calling things asynchronously as appropriate.
Fleshed out launching mappers in worker.go
Fleshed out reducer in worker.go. Also changed output of reducer to a
list of pair as opposed to a map of string, string.
Added code to split data and send to mappers in server.go

Merge branch 'multinode' of
https://github.com/EEL6935022ATeam10/GoMapReduce.git into multinode
Fixed bugs. still working on more.
Merged in latest version of examples with input data sets. Also multinode map reduce now works for 1 master & 1 worker
Trying to fix bug with reading incomplete json data.
single master & worker wordcount now works.
Multinode map reduce works. The only limitation is that all the workers
must be up and running before the master. The config file needs to be in
a specific format (each line contains rank and ip:port, no blank lines).
Each example will now be launched using command line flags like so :
./word_count -rank=2 -config=config_file -inputdir=datainput
Changing the folder names according to go coding standards
Deleting duplicate files
change in time display to ms
