[jmisur]

Fixes #248
Also improves SARD/SRD mix example.

Code changes look code except for the removal of the system-dependent line separator. There is also one failing test:

[fbenz]

Are you intentionally removing the system-dependent LINE_SEPERATOR? I would suggest to keep it and move to a single LINE_SEPERATOR constant instead of having several ones across the tests.

[jmisur]

I replaced this ugly looking constant with fixLineSeparator() used in tests.
