VERY BASIC snippets of code that I find myself using all the time. Maybe they are useful for you too? Who knows. They are here for personal reference.
Each snippet is inside a folder and has a main program. Sometimes there are other classes too.
The Commons folder contains common methods used by all the snippets. They are defined as
