Print out engine's name instead of simple name

[Sangbaek]

Simply replace engine.getClass().getSimpleName() with say, a simple variable like engine_long_name, which is

def engine_long_name = engine.getClass.getName()

if getName method exists in the class. Maybe use try catch or ?.

Low priority but it would be nice to print the progress without duplicates.

Interestingly, this is solved by the PR #406 .

So I should test if it's good to roll back the commit 2137f90 for src/main/java/org/jlab/clas/timeline/run_analysis.groovy

Will do later this week.
