no varnames in Moran_BV_matrix

[slumnitz]

Moran_BV_matrix object takes varnames as input, but this argument does not seem to be used anywhere in the function.

For labeling moran_facette() plots (starting to prototype facets), it would be great to either include this list as an attribute of the Moran-BV_matrix Object, or even allow for varnames input in the Moran_BV Object.

What do you think @sjsrey @darribas @ljwolf?

I think it'd be great to store the varnames on the object and use them when needed. By default these should be ['x{}'.format(i) for i in range(p)] for an (n,p) input matrix.

@ljwolf thank you for the tip: #23 should deal with this
