 * \file file_configuration.cc
 * \brief Implementation of the interface ConfigurationInterface that reads the
 * configuration from a file.
 * \author Carlos Aviles, 2010. carlos.avilesr(at)googlemail.com
 *
 * This implementation has a text file as the source for the values of the parameters.
 * The file is in the INI format, containing sections and pairs of names and values.
 * For more information about the INI format, see http://en.wikipedia.org/wiki/INI_file
