MPG() parameters to be removed

[ecologics]

filterPatch and spreadFactor are no longer used, as they were Andrew Fall's parameters.

The first is still useful, but I think it needs to be up to the researcher to prefilter out patches below a threshold number of cells. There is always a danger in helping the user too much! What do you think @achubaty? Too many patches can be hard to interpret. And one cell patches are also of questionable utility and accuracy. Worth implementing?

The second is a legacy option from Andrew Fall and allowed control over how graph was extracted for speed purposes. It could be that variance in Sam's implementation with respect to this variable is leading to differences in resulting graph. Not relevant, so remove.

sa parameter. See discussion in other issue (#23).

[achubaty]

filterPatch: will remove, but perhaps we add an example where we pre-filter a raster to show how its done.

spreadFactor: will remove

sa: removed with #23

[ecologics]

Agreed! Example to show how to pre-filter a raster, rather than providing wrapped functionality.

[achubaty]

@ecologics I'm about to push the removal. Can you add the example?

[ecologics]

Sure thing. Close this issue, I'll make another one so that I can keep track of what I need to do.

[achubaty]

pushed. please reference this issue in the new one.
