Created script for testing locally.

Simulates N iterations of the two sequential steps (assuming one map
task and one reduce task).

Needs to be updated in order to automatically repeat the commands until
the process reducer returns the required final output.
Merge branch 'master' of github.com:visemet/rankmaniac
Fixed off-by-one error.

Always runs at least 1 iteration.
Basic attempt at pagerank-reduce function.

Sums together the partial pageranks computed by the pagerank-map
function, and outputs the new information of each node to be used in
the next iteration.
