Please report any typos or suggest improvements, e.g. another way to represent the American subperiods. I might implement the colour scheme as well in future.
strat2file is the code just to convert excel spreadsheet to JSON, XML etc.
strat2my is a function that takes a string of geological time and convert it to a number, e.g. Permian to 'average age', start and end: get_time('Danian') (63.8, 61.6, 66.0)
