added a function to extract summary elements from linear model, ran regression of M and leaf#, saved this output into new stats output folder
added approxfun function to functions script, added leaf area and leaf number interpolations to calculated data fodler, renamed leaf interpolation script
renamed so this is deleted
carbon budget now takes results from Mmodel to calculate M based on leaf number for each id, then uses Amodel to get C per day (right now seems to be a unit conversion issus as gC to low)

***also the M for free plants seems to be off
