added code to remove treerings - they degrade the recon. Have just run all_prox and climvar(_noTR) using this and the other bits added
ENSOReconstruct excludes TR now. also makes vars global for proxyCont. ProxyContribution calcs obs.per.time and have added object adn to ENSOReconstructSuite for appending things to filenames
ENSOReconstruct trange now calcs min number of obs to be plotted as floor(max/4). this works fine for the numbers I have now - ts (7) goes to 1, pr (40) goes to 10
