/*
 * The custom allocator for this project was created for preventing memory
 * leaks. It uses a simple singleton `ft_get_alloc()` to get the pointer to the
 * root of a linked list. Each calloc allocates a new node in the linked list,
 * the custom free only frees a pointer allocated by the custom allocator. The
 * `ft_clean()` function clean all memory allocated by the custom allocator.
 * This ensures that all allocations can be dealocated by the end of the
 * program, just by calling `ft_clean()` on the end of it.
