• Fixes to find_by_perl
  Can now be accessed in an object or namespace flexibly.
  Now ignores case of keys.
  Keys with underscores can be used.
  Will work properly when passed a single node instead of an array reference of nodes.
  
• Fixes to xget
  Method of deferencing has been changed to be compatible with newer versions of perl ( 5.10.2+ )
  
• Fixed handling of nodes named 'value'; they will no longer crash the XS code
  
• Added a new function similar to new called 'simple', that works in the same way but automatically uses the 'simple' parser
  
• Altered handling of node values in simple mode, so that it stores values when mixed with nodes or atttributes under 'content' ( like XML::Simple )
  This feature was requested by users so it has been added. Note that it only does this when the value is not composed of just spaces and carriage returns.
