This function uses the python built-in `property()` to create attributes
to access the bit fields of a function directly.
The field_list should contain a list of properties where each property is
defined as a tuple of the form:
(bit_mask_variable, bit_field_name, bit_field_mask)
After this function has been called, you should be able to get and set
the bit fields using the `bit_field_name`.
