Message:

WHAT:

1) Added comments explaining why empties_tree_inherit size>1.
2) Added enum_base<index0> speecialization.

WHY:

1) Clarify why using inheritance to achive EBO only works

with 1 level of inheritance.

2) Show further saving of one_of_maybe vs. variant.

OUTPUT:
sizeof(empty_class<0>)=1
sizeof(index_inherit<0,empties_inherit>)=1
sizeof(empties_inherit)=1
sizeof(empties_tree_inherit)=2
sizeof(empties_member)=2
sizeof(empties_all_of)=1
sizeof(empties_tree_all_of)=1
sizeof(empties_variant)=8
sizeof(empties_one_of)=1
sizeof(enum_base<index0>::type)=1
