What is a Model Query Builder Macro?

In AdonisJS, macros provide us a way to easily extend internal AdonisJS classes with our own methods. A lot in AdonisJS is macroable, including the request, response, and query builder.

When we add a macro, that function will then be readily available to use with instances of whatever class it is we've defined that macro. In the case of the Model Query Builder, adding a macro will make that function available within all model's query builders.
