nodeToDF

Converts the list-style-genealogy to a data frame, where each variety has an id value
and references its' parent's id value. ID value ranges correspond to generation.
It is possible that with more complex genealogical structures the range of id values may need to
expand to reduce the probability of two varieties being assigned the same id value.

Methods for searching through genealogical data and displaying the results. Plotting algorithms assist with data exploration and publication-quality image generation. Includes interactive genealogy visualization tools. Provides parsing and calculation methods for variables in descendant branches of interest. Uses the Grammar of Graphics.
