`site`	A dataframe with the six fields: record - a unique, consecutively numbered identifier per site site - a unique identifier per site slope - slope in degrees wind - velocity in km/h temp - ambient temperature deg. C dfmc - moisture content of fine dead fuels in whole numbers (eg 0.1 for 10 litter - weight in t/ha of fine dead organic material forming the O horizon fline - the fireline length in m
`Structure`	A dataframe with the fields: record - a unique, consecutively numbered identifier per site site - a unique identifier per site NS, El, Mid & Can - the mean separation between plants (m) per stratum ns_e, ns_m, e_m, e_c, m_c - Logical field indicating whether plants in the stratum on the left grow directly beneath those in the stratum on the right. Acceptable values are t, f, or blank, where the outcome will be decided by the relative stratum heights.
`Flora`	A dataframe with the fields: record - a unique, consecutively numbered identifier per site species - the name of the species, which will call trait data from 'default.species.params' moisture - the moisture content of the species in whole numbers (eg 1 for 100 stratum - numeric value from 1 to 4, counting from lowest stratum comp - hc, he, ht, hp & w - canopy dimensions for that species (m) clump - mean ratio of clump diameter to crown diameter openness - proportion of plant canopy occupied by gaps between clumps
`default.species.params`	Leaf traits database
`a`	The record number for which to build the table
