Miscellaneous minor changes and starting to think about random effects.
Starting to lay framework (non-functional!) for random effects
NON-FUNCTIONAL - More additions to random effects
Functional random effects by plot.
Improved ability to parse spectra names.
Fixed spectra names in ASD and SE files. Moved canopy and transmittance spectra to different folder pending further understanding.
Improved initial conditions based on Jacquemoud paper (same as priors). Changed initial write to append=FALSE to overwrite files on fresh runs.
Reduced ngibbs.
Added RE suffix for random effects.
Removed canopy and transmittance from folder.
Included coda library for better mcmc diagnostics.
Individual leaf effects. Added conditional on spec error function for dealing with one-column errors.
