All code to date assumes the user knows how many endmembers to expect. There are methods in the literature for estimating the number of endmembers from the data itself. We should consider adding one or more of these to the package, time permitting.

Methods for finding the number of endmembers (recommended in Harsayni2012)
- hfc (hfcVAR and hfcSAMPLE)
- nwhfc
- sml (second moment linear)
- Hysime (hyperspectral signal subspace identification by minimum error)

Finding the number of endmembers is definitively an issue.
