Go implementation of an expiring key-value map
Install expiring-memory-store using the "go get" command:
go get github.com/skidder/expiring-memory-store/ems
The Go distribution and concurrent-map (a thread-safe map for Go) are the only dependencies.
Run the test suite from the ems directory:
$ git clone https://github.com/skidder/expiring-memory-store.git
$ cd expiring-memory-store/ems/
$ go test
PASS
