[Rock-dev] API change in typelib (read on!)

[Sylvain Joyeux]

The context
-----------
In the ruby API of typelib, when you get a type object type_t that 
describes a compound (struct, class), one can get the type of the fields 
by calling type_t.field_name.

Example:

   struct Bla
   {
      int a_field;
   };

in ruby:

   bla_t = registry.get('Bla')
   a_field_t = bla_t.a_field

at the end, a_field_t is an object describing the 'int' type

This is the source of all the "WARN: cannot define the method ...." you 
are seeing these days.

The change
----------
Since there are so many clashes with normal ruby methods, I'll remove 
that feature -- it is anyway mostly unusable. The removal is scheduled 
at the end of next week.

If you *are* using it (something I would be surprised about), replace

   bla_t.a_field

by

   bla_t['a_field']
