join_with_slash.py

"""
Both URL and file path joins use slashes as dividers between their parts.
For example:

path/to/dir + file --> path/to/dir/file
path/to/dir/ + file --> path/to/dir/file
http://algorithms.com/ + part --> http://algorithms.com/part
http://algorithms.com + part --> http://algorithms/part
