Docker environment building

[mzks]

Is your feature request related to a problem? Please describe.
I'm always frustrated when I prepare the simulation and an analysis environment.
The main two large packages are ROOT and Geant4.
For Geant4, an optional data file should be also installed.

Describe the solution you'd like
Prepare docker environment.
It's easy to make Dockerfile with building everything in Dockerfile.
However, I'm interested in only two packages that have already provided.
I need smarter way to make them.

Describe alternatives you've considered
Everything can be prepared with much long self-build Dockerfile.

Additional context
If possible, it is convenient to work with VS code.
