Prato is a library that simplifies the backend code required to support queryable data, by mapping parameters onto a table structure, allowing Prato to invoke Active Record methods like `.where`, `.order`, `.joins`, `.pluck` and others. The immediate use case for this is fetching data for tables in the frontend, and with a simple *Prato* table, it becomes trivial to provide any kind of filtering / sorting / pagination operations over an Active Record relation.
