nl_tokens: Converts an array of diffs to array of values for example : [ 100 1 1 1 1 1 ] = > [ 100 101 102 103 104 105 ]
pl_tokens: function ( diffArray ) { for ( var i = 0 , head = 0 , result = [ ] , len = diffArray . length ; i < len ; i ++ ) { <mask> = head + diffArray [ i ] ; result . push ( head ) ; } return result ; }
