Implementing support values and fixing issue when external parentheses are missing.
Using regex tokenizer instead of character iteration for better readability and slight performance boost.
Adding docstring for new_clade method.
Adding additional Newick test file with quoted node labels and node comments.
Adding test NEXUS file from TreeBASE.
Break out of for loop when ; is encountered, and make sure that no tokens remain.
