master and node from adam

master is started like ./master #_OF_WORKERS JOB_TYPE
where #_OF_WORKERS is the number of worker nodes already running
and JOB_TYPE is either i (indexing) or q (query)

node is the worker , started like ./node WHICH_NODE TOTAL_NODES
where WHICH_NODE is the number indicating which node (1-MAX) this worker
is
and TOTAL_NODES is that MAX (also the same number passed to ./master's
first argument)

the mapping step of indexing is done and reducing is about 70% done.
