// Example of aggregating channel values into sets based on a key.
// In this case, we aggregate strings by their first letter.
// Aggregated groups are emitted as slices when one of the following is true:
//  - the buffer capacity is reached (set to 2 in this demo so we can hit it easily with the test data)
//  - no new items have shown up for that group for two seconds
//  - the source channel is closed
//
// The primary use case for this sort of thing is in forming higher-level transactions from an event stream,
// such as aggregating a log of actions by userid into a set of events that represents a session.

# This generates tree.h by packing a set of strings into a Radix Tree structure.
