struct Object* find_basis_mball	(	Scene *	scene,

This function finds basic MetaBall.

Basic MetaBall doesn't include any number at the end of its name. All MetaBalls with same base of name can be blended. MetaBalls with different basic name can't be blended.

warning!, is_basis_mball() can fail on returned object, see long note above.
