Bump to 0.1.9.dev0
Define c wrappers in a dummy class
Do not run MetaSimObject in subclass

At this point `_cwrap_*` cannot be used in subclasses.  This is
backward-incomplete change.
Add TestVectCalc.test_super_in_baseclass
Put CFuncHolder at the end of `bases` (fixes test)

Note that this order did not work at the point it was introduced
e2c2e73a442032f816bcf61f2ba685741be3f47a.
Add comments on MetaSimObject
Merge branch 'cfunc-super'

- C functions can be accessed via `super`.  This eliminates the need
  for the `cwrap_*` function.
- `cwrap_*` function defined in subclasses are not executed anymore.
  This change is backward-incompatible.
