Paper - Improved second pgh, added figure placeholder, changed plotting in figure X (turnover through time).

Readme - added link to the raw paper for users on github.

Calcualteturnover - left calculate_turnover as a bigger matrix (didn't remove samples) and instead created a boolean variable. Added some extra info for the turnover estimates (abs. min. dist, dist to self, sampe size, self.size).  Made neccessary changes to the runs.

Added some comments, tried to see if an RDA could help understand if there are any common features for the 95%CI samples, but got stuck with compiled.pollen length being dfferent than rep.frames (thus changes above).

Crop compiled.pollen in lad_datasets, not in calculate_turnover.

Re-ran turnover, new rep.frame.RData

Added gitignore
