Standalone CLI example fails in Matlab 2019a

[ujhelyiz]

When trying to execute the latest 0.8.0 snapshot version of the standalone CLI example (https://build.incquerylabs.com/jenkins/job/Massif/job/master/lastSuccessfulBuild/artifact/releng/hu.bme.mit.massif.simulink.cli-package), it failed with the following trace:

massif_functions.m is missing from the Matlab path (this root cause is not visible due to #191). We should discuss how this should be handled.

• Automatically load massif_functions.m #156
• Document adding massif_functions.m to the Matlab path #198
