Remove trailing spaces in SAC model parallel line
Split line and parallel line models into separate 'cpp' files
Fix documentation for SAC model parallel line

Fix angular distance condition in SAC model parallel line

provided by user, while according to the name of the class and
documentation it should rather check if the line model is parallel to
the axis.
Add a test for SAC model parallel line

Additionaly rename test_sample_consensus_line_model to reflect the fact
that now it tests multiple line models.
