Calculates the weights from two vectors of minimum and maximum dating for each object. Returns a dataframe with the weight in the first column and FALSE in the second if two rows have the same value in both min and max dating. See [publication](https://doi.org/10.1017/aap.2021.8) for information about how this is calculated.
get.weights(DAT_min, DAT_max, verbose = FALSE)
a vector of 'weight'-values for the datsteps-data.frame, that is a quantification of how well the object is dated (lesser value means object is dated to larger timespans, i.e. with less confidence)
a numeric vector containing the minimum date of each object
a numeric vector containing the maximum date of each object
TRUE / FALSE: Should the function issue additional messages pointing to possible inconsistencies and notify of methods?
