baseDir has been deprecated

[JohnHadish]

Description of the bug

GEMmaker uses the script implicit variable baseDir in several of its example scripts. As of 20.04.0 Nextflow has deprecated baseDir and instead prefers user to use projectDir and launchDir. https://www.nextflow.io/docs/latest/script.html

We already use the projectDir nomenclature when reporting directories at the beginning of GEMmaker. baseDir references should be changed everywhere within GEMmaker.
