Workflow for Web Archive Content Characterisation using Fits.

The workflow uses Spacip (https://github.com/shsdev/spacip) to prepare ARC web is a tool to prepare ARC web archive container files by unpacking the compressed files in HDFS and creates input files which can be used by Tomar (https://github.com/openplanets/tomar). After merging the mapper output files from Spacip (MergeTomarInput) into one single file, it can be used by Tomar as input. The tool invokation depends on a tool specification file which must be available in HDFS, this is explained in the Tomar documentation.
