Flow control for holds


I'm merging two previously-submitted ideas into one that allows users to control the flow of their holds. 

The previously-mentioned use cases are below:


- The ability to maintain a Netflix-style queue where patrons can control the order in which a batch of holds is received. The order could be based on the sequence of a series or a sequence determine by the user.

- The ability to control how many books / DVDs, etc. the patron receives at one time so that all of their holds don't arrive at once. 

- The ability for a patron to say they just need one or two of several titles they put on hold. 

- Several editions of a book meet the patron's needs, but they need more fine-grained control than current meta-holds.

I have placed the other two ideas in the attic, but have moved their 'likes' to this idea. See http://masslnc.org/node/2626 and http://masslnc.org/node/3041
