`NMFSeed` is a constructor method that instantiate `NMFSeed` objects.

NMFSeed is a constructor method that instantiate NMFSeed objects.

NMF seeding methods are registered via the function setNMFSeed, which stores them as NMFSeed objects in a dedicated registry.

removeNMFSeed removes an NMF seeding method from the registry.

  NMFSeed(key, method, ...)

  setNMFSeed(..., overwrite = isLoadingNamespace(),
    verbose = TRUE)

  removeNMFSeed(name, ...)

`key`	access key as a single character string
`method`	specification of the seeding method, as a function that takes at least the following arguments: object uninitialised/empty NMF model, i.e. that it has 0 rows and columns, but has already the rank requested in the call to `nmf` or `seed`. x target matrix ... extra arguments
`...`	arguments passed to `NMFSeed` and used to initialise slots in the `NMFSeed` object, or to `pkgreg_remove`.
`name`	name of the seeding method.
`overwrite`	logical that indicates if any existing NMF method with the same name should be overwritten (`TRUE`) or not (`FALSE`), in which case an error is thrown.
`verbose`	a logical that indicates if information about the registration should be printed (`TRUE`) or not (`FALSE`).

NMFSeed: signature(key = "character"): Default method simply calls new with the same arguments.
NMFSeed: signature(key = "NMFSeed"): Creates an NMFSeed based on a template object (Constructor-Copy), in particular it uses the same name.
