Automatically ignore large files/folders and sync code workspaces using syncthing

Syncthing is a great open-source software to easily sync files and folders across devices. GUI snap from their website -

I wanted to sync my coding workspace across my laptop and desktop computers so that I can seamlessly switch between them at any time.
Usually, this is not done due to the following issues -

1. Some file/folder sizes can be very large
2. Build files do not match due to different processors on different computers

/*
This program outputs a list of files/folders in the filesystem, that are above an inputted SIZE_LIMIT and are reasons for
upper directories being above the SIZE_LIMIT. Upon removing these files/folders, no other paths will have a size 
above SIZE_LIMIT.

For example,

SIZE_LIMIT = 100MB
File system:
/mnt/d/folder1 1000 MB

In this gist, I'll describe steps to do this.

0. Install Docker

1. Pull the docker image
