## TODO:
## - include a 'sequence' column to show the points in sequence
## - need an 'id' for polygons with holes, and non-simple (i.e., a polygon defined by two regions)
## - decode_pl() to accept a vector of polylines
## - methods for polylines
## -- length
##
## - if 'SimplifyPolyline' is called on a 'sdt_polyline' column, return a 'spdt_polyline column
##
## - re-building the package prevents := from working
##
## - specify all arguments should be columns of the data.table?
## --- exemplified by dtDestination, the 'distance' value must be
## --- a column / vector of values, otherwise if only one value is
## --- supplied, it's only treated as one value and only used
## --- on the first row, thre rest of the rows will assume
## --- distance == 0
## -- or, if a single value is supplied, assign it to ALL ROWS
