Estimating Entity Importance via Counting Set Covers - SIGKDD 2012
-------------------------------------------------------------------------------

Usage: 
ImportanceSampler <entities File> <seed File> <outputFile> <number of iterations>

entities file: the file containing the entities to be evaluated. One line per entity. 
Two tab-separated fields per line. First field is the id/label of the entity. Second field is the
multiplicity of the entity (e.g. people with the same skillset).

seed File: the file containing the collection of all minimal covers. One minimal cover per line.
Each cover is a space-separated set of numbers. Each number corresponds to the order of the corresponding 
entity in the entities file.

outputFile: the file to which the counts are written

number of iterations: the number of iterations for the sampler

-------------------------------------------------------------------------------
ImportanceSampler.java: Implements the entire importance sampler methodology

MinimalSolution.java: Represents a minimal cover

Pair.java: a comparable container for a pair of values
