+/*!
+ This class implements RFC 6901 "JavaScript Object Notation (JSON) Pointer"
+ (https://tools.ietf.org/html/rfc6901).
+
+ A JSON pointer is for identifying a specific value in a JSON document
+ (GenericDocument). It can simplify coding of DOM tree manipulation, because it
+ can access multiple-level depth of DOM tree with single API call.
+
+ After it parses a string representation (e.g. "/foo/0" or URI fragment
+ representation (e.g. "#/foo/0") into its internal representation (tokens),
+ it can be used to resolve a specific value in multiple documents, or sub-tree
+ of documents.
+
+ Contrary to GenericValue, Pointer can be copy constructed and copy assigned.
+ Apart from assignment, a Pointer cannot be modified after construction.
+
+ Although Pointer is very convenient, please aware that constructing Pointer
+ involves parsing and dynamic memory allocation. A special constructor with user-
+ supplied tokens eliminates these.
+
+ GenericPointer depends on GenericDocument and GenericValue.
+
+ \tparam ValueType The value type of the DOM tree. E.g. GenericValue<UTF8<> >
+ \tparam Allocator The allocator type for allocating memory for internal representation.
+
+ \note GenericPointer uses same encoding of ValueType.
+ However, Allocator of GenericPointer is independent of Allocator of Value.
