 * When run, EvoSuite generate tests in a specific folder.
 * New runs of EvoSuite can exploit the tests in such folder, and/or modify them.
 * 
 *
 * 
 * So, with "export" we can copy all generated tests to a specific folder, which
 * by default points to where Maven searches for tests.
 * If another folder is rather used (or if we want to run with Maven the tests in the default EvoSuite folder),
 * then Maven plugins like build-helper-maven-plugin are needed
