init_rSFSW2_project: Initialize a 'rSFSW2' project (setup description file)
In DrylandEcology/rSFSW2: Simulation Framework for SOILWAT2

This function creates/loads an object SFSW2_prj_meta based on the file fmetar containing the descriptions/metadata for this simulation project. The file should be comparable to file.path(system.file("demo", package = "rSFSW2"), "SFSW2_project_descriptions.R")

init_rSFSW2_project(
  fmetar,
  update = FALSE,
  verbose = TRUE,
  print.debug = FALSE
)

`fmetar`	A character string. The path name to the project description file.
`update`	A logical value. If `TRUE`, the path names are re-scanned from `fmetar` and updated values are stored in `SFSW2_prj_meta`.
`verbose`	A logical value.
`print.debug`	A logical value.
