Prefix filenames

[phwizard]

Recommendation from https://www.webfx.com/blog/web-design/wordpress-plugin-development-tips/:

Name Plugin Files Uniquely
Don’t forget that your plugin will be installed in a “busy ecosystem”, perhaps even at the same time as your competitors’ plugins. Unique names for your files and variables are essential. The easiest way to do this would be to prefix custom PHP variables, classes, functions, CSS selectors, and file names with your plugin’s name.
