Arguments

dir_out	where should csv files be sent
n_core	number of corest to run process on
fusion_path	where is gridmetrics.exe (FUSION)
cellsize	output raster resolution
outlier	c(-5,500) range of inclusion
fusion_switches	other fusion switches as a string e.g. "/noground"
xmn, xmx, ymn, ymx	set extent for analysis
fun	a custom function if gridmetrics is not used
temp	temp folder to hold batch files for use with gridmetrics.exe
dir_dtm	in case path to dtms has changed from lasR_project
dir_las	in case path to las has changed from lasR_project
skip_existing	skip tiles if they already have output csvs
existing_coms	path to existing batch comamnds, incase processing was interrupted the first time
lasR_project_csv	csv file of intersections created by lasR_project() function
lasR_project__gpkg	polygon file of intersections created by lasR_project() function
heightbreak	Height break for cover calculation
minht	set minht for gridmetrics.ex
first	T/F use only first returns
intensity	T/F include intensity metrics
fast_cache	experimental - a high-speed temporary folder to copy las files to
n_cache	experimental - number of las files to copy to cache
con	a parallel connection, optional, function can also create parallel threads
