Allows one to parse a cron expression into human readable text (as well as other things but I suggest using @mtdowling's cron-expression for those).
Only supports English for now.
It is a (very slightly) modified version of the script used here.

| * Plugin: StreamlineFoundation | |
| * | |
| * Class: Schedule | |
| * | |
| * Description: Provides scheduling mechanics including creating a schedule, testing if a specific moment is part of the schedule, moving back | |
| * and forth between scheduled moments in time and translating the created schedule back to a human readable form. | |
| * | |
| * Usage: ::fromCronString() creates a new Schedule class and requires a string in the cron ('* * * * *', $language) format. | |
| * | |
| * ->next(<datetime>) returns the first scheduled datetime after <datetime> in array format. | |
| * ->nextAsString(<datetime>) does the same with an ISO string as the result. | |
| * ->nextAsTime(<datetime>) does the same with a UNIX timestamp as the result. | |
| * | |
| * ->previous(<datetime>) returns the first scheduled datetime before <datetime> in array format. | |
| * ->previousAsString(<datetime>) does the same with an ISO string as the result. | |
| * ->previousAsTime(<datetime>) does the same with a UNIX timestamp as the result. | |
| * | |
| * ->asNaturalLanguage() returns the entire schedule in natural language form. | |
| * | |
| * In the next and previous functions, <datetime> can be a UNIX timestamp, an ISO string or an array format such as returned by | |
| * next() and previous(). | |
