returnMin() always returns with the total memory

[szilvajuhos]

Seems returnMin() in nextflow.config is expecting integers:

szilva@galatea ~/dev/forkCAW $ nextflow run test.nf 
N E X T F L O W  ~  version 0.25.6
Launching `test.nf` [prickly_euclid] - revision: 9c68f25573
cat tesERROR ~ No signature of method: returnMin() is applicable for argument types: (nextflow.util.MemoryUnit, nextflow.util.MemoryUnit) values: [16 GB, 104 GB]

 -- Check script 'test.nf' at line: 1 or see '.nextflow.log' file for more details
szilva@galatea ~/dev/forkCAW $ cat test.nf 
println returnMin(params.singleCPUMem * 2 , params.totalMemory)

, so it is always returning with the total memory. Therefore all the memory is assigned to all the time to single processes.
