 /**
  * This class will extract area and population data from the European data
  * source file (EuropeSorted.txt). For each country, it will generate both and
  * AREA and a POPULATION files under
  * org.eclipse.stem.utility\dataMigration\input\AreaPopulationData.
  *
  * To configure, see configuration file :
  * org.eclipse.stem.utility/configuration/EuropeDataExtractor.config
  *
  *
  * To run, add path to configuration file in the run profile (i.e.
  * C:\stemII\org.eclipse.stem.utility\configuration\EuropeDataExtractor.config)
  *
  *
  * Add the following values to the run configuration:
  *
  *
  * C:\stemII\org.eclipse.stem.utility\dataMigration\input\ISO3166-1\ISO3166_1_en.txt
  * C:\stemII\org.eclipse.stem.utility\dataMigration\input\properties\EuropeNames.txt
  * C:\stemII\org.eclipse.stem.utility\dataMigration\input\properties\EuropeCountries.txt
  * C:\stemII\org.eclipse.stem.utility\dataMigration\input\AreaPopulationData\
  *
  * Overview of the data generation process for the Europe data set.
  *
  * 1) Data Cleaning : start by running EuropeDataCleaner. This program will
  * remove all unnecesary data (i.e. columns) in the original source file. In
  * addition, this program will group the data based on its ID (i.e. NO,IT,FR,UK,
  * etc). The result will be a file named EuropeSorted.txt with cleaned data.
  *
  * In other words : Europe.txt --> ||EuropeDataCleaner|| --> EuropeSorted.txt
  *
  * NOTE: EuropeSorted.txt will be used as the input for the remaining part of
  * the process.
  *
  * 2) Data Formatting : run EuropeDataFormatter to break down the data source
  * (EuropeSorted.txt) into multiple data files, one for each country as
  * indicated by the ID (i.e. NO,IT,FR,UK, etc). The result will be multiple data
  * files (i.e. italy.txt, spain.txt, etc). Each file will be found under a
  * folder with same name as the country (i.e. ITALY\italy.txt, SPAIN\spain.txt,
  * etc).
  *
  * 3) Data Converter : run EuropeDataConverter to convert file in cleaned format
  * into Diva format.
  *
  *
  * 4) Area and Population Data Extraction : run EuropeDataExtractor to extract
  * all area and population data.
