VM

Important functions and classes in this module are as follows:

func add_modules(mods): Adds or replaces modules in the running VM. mods should be a list of modules. Note that this function does not import modules: it merely adds them into the VM so that they can then be imported e.g. by import_module.

func find_module(mod_id): Returns the module with identifier mod_id if it exists in the VM, failing otherwise.

func import_module(mod_id): Imports the module with identifier mod_id. Raises an exception if no such module is in the VM.
