Scan API wrappers simplifying application development

[waynecollier-da]

Application developers would like to use a more abstract interface to the Scan API. For example, several application developers have created their own version of the "/updates python script" scan_txlog.py, and they've also requested a script that makes it easy to consume large sets of transactions at once.

There are several possible such abstractions, including filters for each type of transaction reported by /updates, filters by party, filters by key, filters by time range, etc. See e.g. for bitcoin: https://github.com/bitcoinj/bitcoinj

The objective of this work would be to implement five to ten wrappers of the /updates /holdings and or /state APIs in Scan, which application developers find most useful.
