Handle paths using Pathlib and/or os.path.join

[luisaforozco]

Since GL is a package that is going to be used by users in different platforms i.e. windows, linux, macOS, it is necessary that the paths will be platform independent. Currently GL works in macOS and linux but it wouldn't in windows, where the paths are with single or double \ instead of /.

To solve this I propose:

use pathlib:

from pathlib import Path
data_folder = Path("source_data/text_files/")
file_to_open = data_folder / "raw_data.txt"

# It also works concatenating multiple strings on the fly:
>>> a_string = "path/to/something"
>>> a_path = Path(a_string+"/new/directory/type")
PosixPath('path/to/something/new/directory/type')

# and adding a str to a Path
>>> a_path / "new/string/path"
PosixPath('path/to/something/new/directory/type/new/string/path')

and/or also use os.path.join

import os
data_folder = os.path.join("source_data", "text_files")
file_to_open = os.path.join(data_folder, "raw_data.txt")

# This also works concatenating a string and a pathlib Path
>>> ab = Path("test/one")
>>> os.path.join(ab,"other/test/")
'test/one/other/test/'

GL works on windows with anaconda and visual studio. We tested this during the TUSAIL school

Ok, so are you sure this is not needed?

@chyalexcheng I see that in commit c7a86a8 you are amending some paths. Check if what I posted here is useful.
