  * The Doc class is used to parse and navigate a JSON document. The model it
  * employs is that of a document that while open can be navigated and values
  * extracted. Once the document is closed the document can not longer be
  * accessed. This allows the parsing and data extraction to be extremely fast
  * compared to other JSON parses.
- * 
+ *
  * An Oj::Doc class is not created directly but the _open()_ class method is
  * used to open a document and the yield parameter to the block of the #open()
  * call is the Doc instance. The Doc instance can be moved across, up, and
  * down the JSON document. At each element the data associated with the
  * element can be extracted. It is also possible to just provide a path to the
  * data to be extracted and retrieve the data in that manner.
- * 
+ *
  * For many of the methods a path is used to describe the location of an
  * element. Paths follow a subset of the XPath syntax. The slash ('/')
  * character is the separator. Each step in the path identifies the next
  * branch to take through the document. A JSON object will expect a key string
  * while an array will expect a positive index. A .. step indicates a move up
  * the JSON document.
