Parameters
----------
items : [object[, ...]]
A list of items to make members of the association.
meta : dict
A dict to be merged into the association meta information.
The following are suggested to be assigned:
- `asn_type`
The type of association.
- `asn_rule`
The rule which created this association.
- `asn_pool`
The pool from which the exposures came from
- `program`
Originating observing program
product_name_func : func
Used if product name is 'undefined' using
the class's procedures.
acid : str
The association candidate id to use. Since Level2
associations require it, one must be specified.
Notes
-----
This is a low-level shortcut into adding members, such as file names,
to an association. All defined shortcuts and other initializations are
by-passed, resulting in a potentially unusable association.
`product_name_func` is used to define the product names instead of
the default methods. The call signature is:
product_name_func(item, idx)
where `item` is each item being added and `idx` is the count of items.
