Listen on a channel to trigger a function
This is just a little piece of test code for my larger alarm clock build. This program has multiple goroutines sending to a channel, and a main function listening to the channel. Depending on what goroutine sends, the main function executes different responses. This is to test having multiple alarms going off at different times, sometimes even interrupting each other (which we'll eventually need the context package for)
the main issue with the code as it stands is that if all alarms are turned off, there will be a problem with deadlock, unless the channel is closed, in which case main will exit. The solution to this is most likely to have all of these things in tools, and have the main web server running and calling these functions from tools as needed. There will need to be some sort of check() function to see if any alarms are running, since if there are not then listen() will need to be called again
