nl_tokens: Converts an array of number values to array of differences between each pairs of values for example : [ 100 101 102 103 104 105 ] = > [ 100 1 1 1 1 1 ]
pl_tokens: function ( numArray ) { numArray . sort ( function ( a , b ) { return a - b ; } ) ; for ( var i = 0 , prev = 0 , diff = 0 , result = [ ] , len = numArray . length ; i < len ; i ++ ) { diff = numArray [ i ] - prev ; prev = numArray [ i ] ; <mask> . push ( diff ) ; } return result ; }
