Add embeddings of Hubbard trees into julia sets

[jeffwack111]

• Calculate critical orbit with the spider algorithm
• Calculate the location of branch points with external rays?
• This will require extending the binary function to calculate binary for branch points to find the external angle(s) of a branch point
• Make tree edges straight lines?

[jeffwack111]

Tree edges will be calculated by starting with straight lines and taking repeated preimages

Implemented! There may be future improvements if a path type is ever implemented
