summarize lidar for raster pixels

gridmetrics(las_files, dtm_files = NA, dtm_folder = NA,
  dtm_ext = ".dtm", no_dtm = F, fun = compute_metrics2, xmin = NA,
  xmax = NA, ymin = NA, ymax = NA, res = 66, grid = NA,
  n_read = NA, out_name = NA, return = F, con = NA,
  out_table = NA, ...)

`las_files`	list of paths to las files
`dtm_files`	optional list of paths to dtms
`dtm_folder`	optional folder of dtms
`dtm_ext`	what is the file extension of dtms
`xmin`	(optional) force extent of analysis
`xmax`	(optional) force extent of analysis
`ymin`	(optional) force extent of analysis
`ymax`	(optional) force extent of analysis
`res`	resolution of processing analysis in units of provided lidar / dtm
`grid`	pre-defined raster for analysis - lidar metrics are computed for each cell
`intersect_only`	only provide outputs over areas in which lidar and dtms intersect?
`fns`	list of functions that will be used to generate columns of summary statistics from the las data
