Make unit test use its own folder not /tmp

[marco-foscato]

This block

DENOPTIM/src/test/java/denoptim/io/DenoptimIOTest.java

Line 450 in 5188862

String tmpFile = FileUtils.getTempFolder()

should use the folder created specifically for the unit test (see

DENOPTIM/src/test/java/denoptim/io/DenoptimIOTest.java

Line 88 in 5188862

File tempDir;

) as to avoid conflicts with existing files.

I solved the issue (creating a new branch called devel_tempFile) in this way:

DENOPTIM/src/test/java/denoptim/io/DenoptimIOTest.java

Line 450 in 65c36d6

String tmpFile = tempDir.getAbsolutePath() + SEP + "frags.sdf";
