gadget_directory(dir, mainfile = "main")
gadget_dir_write(gd, obj)
gadget_dir_read(gd, file_name, missing_okay = TRUE)

`dir`	Name of directory, will be created if it doesn't exist.
`mainfile`	Name of the GADGET mainfile to use.
`gd`	A `gadget_directory` object.
`obj`	The `gadget_file`, or `gadget_likelihood_component` to write.
`file_name`	File to read out of the directory and turn into a `gadget_file`.
`missing_okay`	If true, return an empty file instead of complaining that the given file does not exist.

This handles

## Not run: 
# Create a gadget directory
gd <- gadget_directory('./out')

# Read in the likelihood file
likelihood <- gadget_dir_read(gd, 'likelihood')

# Write out an area file to "./out/areas", replacing any existing file
gadget_dir_write(gd, gadget_file("areas", components = list(list(north = 1:3, south = 4:7))))

# Replace a likelihood component if one already exists with
# the same name/type or append it to the bottom
gadget_dir_write(gd, gadget_likelihood_component("understocking", name = "frank"))

## End(Not run)
