Arguments

`clim`	A dataset with the fields: tAM (9am temp, degC) tPM (3pm temp, degC) tMin (Minimum daily temp, degC) tMax (Maximum daily temp, degC) rhAM (9am Relative humidity, rhPM (3pm Relative humidity, wAM (9am wind, km/h) wPM (3pm wind, km/h) cAM (Morning cloud, oktas) cPM (Afternoon cloud, oktas) MSLP (Mean Sea Level Pressure, hPa) Rain (Daily rainfall, mm)
`m`	The starting moisture (proportion ODW)
`LAI`	Leaf area index of the vegetation
`WRF`	Wind reduction factor
`hCan`	Height of the tree canopy (m)
`rholitter`	Density of litter particles (kg/m3)
`litterW`	Weight of litter (t/ha)
`lat`	Latitude (degrees)
`altitude`	(m)
`slope`	(degrees)
`slopeSD`	Standard deviation of the slope
`rangeDir`	Cardinal direction of the ridgelines - either Nth/Sth (0) or west/east (270)
`dt`	Seconds per time step
`cardinal`	Simplify compass directions to cardinal (TRUE/FALSE)
`nelsonA`	Constant from Nelson FMC model
`nelsonB`	Constant from Nelson FMC model
`conLitter`	Litter conductance (m/s). Using value from Matthews spreadsheet rather than paper
`sigma`	Surface area: volume ratio of litter particles (m2/m3)
`EPS`	Sensitivity of iteration
