Simple namespace usage in Buckshot template

gistfile1.xml

<!-- 
  We declare a defult namespace which tells the framework
  which platform elements are in-scope by default.
-->   
<template xmlns='http://buckshotui.org/platforms/html'>
  <!-- 
    without the above namespace declaration, this element 
    will not be found by the template parser
  -->
  <textblock text='hello world' />
</template>
