Trim white-space from values

We currently use this module in our Dancer based ecommerce project Interchange6 thank you for your contribution.   In a few instances we have run into situations with white-space in values.  I have written up a subclass to address this per your POD in Abstract.pm.  Thank you in advance for your time and consideration.  Let me know if you have any questions or concerns.

Warm Regards,

PS I am a newer programmer so feel free to be critical if I did something wrong :)
