Create raster of leading vegetation types and Plot a bar chart summary and a vegetation type map. NOTE: plot order will follow colors order.

plotVTM(speciesStack = NULL, vtm = NULL, vegLeadingProportion = 0.8,
sppEquiv, sppEquivCol, colors, title = "Leading vegetation types")

## Arguments

speciesStack A RasterStack of percent-cover-by-species layers. An optional vegetation type map (RasterLayer). If not supplied, will be produced internally by makeVegTypeMap. The minimum proportion cover required to consider a species to be the "leading" one. Default 0.8. a species equivalency table TODO: description needed the column name to use from sppEquiv. Named vector of colour codes, named using species names. NOTE: plot order will follow this order. The title to use for the generated plots.
