anylist 0.6.4

a list type for any type
Documentation
# AnyList

 AnyList works as a Vec<T> but without generics in it's type.
 
 without having a generic it's type, you can make a list of lists that
 have different types.

 the only issue this creates is having to use the correct type
 in every function because all of them need a generic, exept for
 the implementations that don't need it on their arguments(ej: remove, pop).

 if a wrong type it's used, then the API will panic.

 the only purpose of this is to out perform an Vec<Box<Any>>, which
 generates fragmentation and indirection, with an extra pointer. and
 to be able to use implementations like pop and remove, without needing
 generics in their functions.

 # Example:
 ```
 fn main() {
    let mut list = AnyList::new::<u32>();

    list.push::<u32>(1);
    list.insert::<u32>(1, 2);
    list.push::<u32>(3);

    assert_eq!(list.as_slice::<u32>(), &[1,2,3]);

    list.untyped_remove(0);

    assert_eq!(list.as_slice::<u32>(), &[2,3]);

    list.untyped_pop();

    assert_eq!(list.as_slice::<u32>(), &[2]);
    
    list.insert::<u32>(0, 1);
    
    for i in 0..list.len() {
      println!("{:?}", list.get::<u32>(i).unwrap())
    }

    assert_eq!(list.as_slice::<u32>(), &[1,2]);
 }
 ```
