can't control edge with debuggerAddress

[chengair]

can't control edge opened with debuggerAddress

line 57 in splinter\driver\webdriver\edge.py is:
options = Options() or options

maybe it should be:
options = options or Options()

test code:will open a new edge ,that is not we expected

from selenium.webdriver.edge.options import Options
edge_options = Options()
edge_options.add_experimental_option("debuggerAddress", "127.0.0.1:9223")
browser = Browser('edge',options=edge_options)
