Currently '.replace' method is used to replace hy objects. This is not safe when we are not sure if the 'obj' in 'obj.replace(other)' is an instance of HyObject. In these cases, we can use function 'replace_hy_obj(obj, other)' instead. This function will try to wrap 'obj' if it's not an instance of HyObject. This also means that we need a wrapping function in hy.models'. Hence I moved the '_wrap_value' function from hy.macros into hy.models. To avoid circular importing, the wrapper functions are provided individually by each model type's own file.
