The project currently raises raw Exception objects. This is considered bad practice and makes it hard to capture just those raised by the library.

We should create a base exception that will be used for this library.

Expose a new tryParse method that will return null if failed to parse the relative string.

This is a well-needed client-side alternative to something like https://github.com/tj/go-naturaldate -- nicely done and thank you!

Here are a few additional forms to consider:

• last [week|month|quarter|year] / next [week|month|quarter|year]
• enhancing timeframes to have shorthand forms (e.g., "d" for day, "w" for week, "m" for month, "h" for hour, "min" for minute, "s" and "sec" for second, etc.)
• enhance direction to support "from now" to indicate in the future
• if possible make the comma in the duration_chain optional (e.g., support things like 2 hours 25 seconds ago instead of hours, 25 seconds ago)
• enhancing duration_chain to support an alternate form where a time is specified instead of an additional duration, e.g., 7 days ago at 12:35pm or tomorrow at 7:05:35

Also, consider enhancing the grammar expression to support adding or subtracting another relative period, e.g., something like:

expression => relative (("+"|"-") duration_chain)?

This would enable expressions like:

• now-4d
• 7 days ago + 12 hours, 25 minutes

The parse currently only understands relative datetimes. The previous update (#5) added support for adding and subtracting duration from DateTime using + and '-' respectively. This currently lacks support for parsing precise DateTime strings such as 18:20:30.

This should add support for parsing the following strings.

• 12:00
• 12:30:00
• a hour from 00:00
• 12 minutes 5 seconds + 12:00

This issue is derived from #4.
