metamer 0.3.0

Breaking chances

This version overhauls the code and syntax.
It makes it pipe friendly and includes new arguments and changes some of the existing ones.

New features

• The new stop_if argument replaces the old N argument.
  This allows for more flexible and complex stopping criteria than just the number of iterations.
  See ?stop_conditions for a list of implemented functions.

• The new keep argument replaces the old trim argument.

(see ?stop_conditions).

0.2.0 - Outrageous Orange

New features

• Added fortify() method to plot metamers directly with 'ggplot2'.

• The perturbation argument in metamerize() can now be a vector of equal in
  length to change

• Multiple minimization functions can be passed to minimize.

• Added function mean_self_proximity() that computes the inverse of the mean
  minimum distance between each datapoint. Pass it to minimize if you don't want
  it to clump.

• Small speed improvement.
