erase_module(+Module)
Erase the given module Module.  
- Module
- Atom.
Description
    erase_module/1 erases the given module.  This means that the module
    will not exists any more.  All predicates and data (non-logical variables,
    records, etc) defined in the module will be destroyed.  Subsequent calls
    to the module's exported predicates will raise 'undefined procedure'
    errors.
    If the Module does not exist, erase_module/1 simply succeeds.
    An error (101) is raised when trying to erase a module from within itself.
    Note that a module gets erased (and re-created) implicitly when the
    compiler encounters a module/1 directive and that module already exists.
Modes and Determinism
Modules
This predicate is sensitive to its module context (tool predicate, see @/2).
Exceptions
- (4) instantiation fault 
- Module is not instantiated.
- (5) type error 
- Module is not an atom.
- (101) trying to erase a module from itself 
- Trying to erase Module from itself.
