Add bulk of sample projects, LMS and resources

Import a large set of projects and resources into the repository: added an LMS application (Python scripts, DB, assets), multiple Sample Projects (games, utilities, tutorials), DataCamp project notebook and datasets, northeastern workshop materials, and numerous zipped Java/Spring example apps (BookClub, DaikichiPathVariables, DojosNinjas) including their build files and artifacts. Also include assorted images, icons, and metadata (.DS_Store entries). This is a bulk import to populate the repo with example projects and supporting assets.
