Attached patch is based on tvondra's last commit 375b072.

Great idea, fixed, I've added a HASHSET_STEP definition (set to the value 13).

Thanks, fixed like suggested, except I used PG_INT32_MIN and PG_INT32_MAX,
which explicitly represent the maximum value for a 32-bit integer,
regardless of the platform or C implementation.

Thanks. I've added a new test, `sql/invalid.sql` with that example query.
Here is a summary of all other changes:
* README.md: Added sections Usage, Data types, Functions and Aggregate Functions
* Added test/ directory with some tests.
* Added "not production-ready" notice at top of README, warning for breaking
changes and no migration scripts, until our first release.
* Change version from 1.0.0 to 0.0.1 to indicate current status.
* Added CEIL_DIV macro
* Implemented hashset_in(), hashset_out()
The syntax for the serialized format is comma separated integer values
wrapped around curly braces, e.g '{1,2,3}'
* Implemented hashset_recv() to match the existing hashset_send()
* Removed/rewrote some tdigest related comments
