[Trellis-developers] changes to error constants

[Shaddy Zeineddine]

Exceptions should always be thrown using TrellisException:

throw new TrellisException();

And now, to make use of the new error constants and messages, do this:

throw new TrellisException(NULL, TRELLIS_E_ERROR_CODE);

Using NULL will tell TrellisException to use the global error message. 
You can still use custom error messages like so:

throw new TrellisException('Error Message', TRELLIS_E_GENERAL);
