Prioritization based on thresholds of several layers

  prioCellThresholdGRASS(input, output, layerWeights,
    threshold, weight, keepTmpLayers = FALSE, overwrite =
    FALSE)

`input`	name of layer in GRASScontaining input values - has to be the same length as `layerWeights`
`output`	name of output layers containing the priority values
`layerWeights`	weights for each `input` layer - has to be the same length as `input`
`threshold`	value above which layer will be prioritized
`weight`	final weight of the resulting prioritization. All values will be multiplied by this value
`keepTmpLayers`	if `TRUE`, temporal layers will be kept
`overwrite`	if `TRUE`, the output layer will be overwritten

Threshold prioritization based on different layers. The final priority value for each cell is based on if the cell is in each layer above or below the threshold.

For each input layer, a temporary layer is created with the name tmp_input\[i\] which is the layerWeight\[i\] if the value of input\[i\] is below threshold, otherwise it is 0.

These temporary layers will not be deleted if keepTemporaryLayers is TRUE.

In a final step, all temporarty layers tmp_input\[i\] will be added up and saved in output.

invisibly returns output layer name
