Dockerfile

### IMPORTANT NOTE:
###
### This Dockerfile builds the Docker image for the MadMiner "heavy-weight" environment.
### The "heavy-weight" environment provides a working installation of MadGraph 5
### and all the necessary sub-dependencies to run Physics dependent steps:
### - pythia8
### - Delphes
###
### Please consider, that even if this Dockerfile definition is extremely similar as the one
### used for the "madminer-workflow-ph" Docker image, it is better not to depend on it,
### given that the common sections between the two will be moved to a MadMiner provided
### "heavy" version image soon enough.
###
