The proposal of this module is to be an fork from core's profile module, which allow other modules to extend the profile types with a faster and cleaner code.
This module is customized for managing an inventory of chemicals for a small laboratory. It defines a new node type "chemical", and a page that presents a listing of the chemical inventory.
The result cache speeds up slow operations by storing function results in a cache table and later, on page execution time, pulling these results from the cache table rather than calculating them.
