WhiteboxTools v1.2.0

• Added the RasterToVectorPolygons tool, which now completes the raster-vector conversion tool set.
• Added the MultiscaleElevationPercentile tool.
• Added the AttributeCorrelationNeighbourhoodAnalysis tool.
• Added the RadialBasisFunctionInterpolation tool, which includes a thin-plate spline mode.
• Added the RasterPerimeter tool to measure the perimeter of raster polygons.
• Added the MDInfFlowAccumulation tool to perform the MD-infinity flow accumulation of Seibert
  and McGlynn (2007).
• Added the InsertDams tool, which can be used to insert impoundment features at a set of points
  of interest into a DEM. This tool can be used in combination with the ImpoundmentSizeIndex tool
  to create artificial reservoirs/depressions.
• Added the HeightAboveGround tool, to normalize a LiDAR point cloud. Each point's z-value is
  converted to the height above the nearest ground-classified point.
• Modified the LidarRbfInterpolation tool to improve efficiency.
• Fixed an issue with how floating point attributes were written in Shapefile attribute tables.
• Updated the LidarSegmentation tool, which now used RANSAC to fit planar models to points.
• Fixed an issue with the Reclass and ReclassFromFile tool that caused striping.
• The Relcass and ReclassFromFile tools now take 'min' and 'max' in the reclass string.
• The watershed tool now accepts either a set of vector points or a raster for the pour points
  file. If a raster is specified, all non-zero, non-NoData valued cells will be considered
  outlet cells and the watershed labels will be assigned based on these values.
• The D8 and D-infinity flow accumulation tools now take either an input DEM or a flow pointer raster
  as inputs.
