@method inGroups(<num>, [padding])
@returns Array
@short Groups the array into <num> arrays.
@extra [padding] specifies a value with which to pad the last array so that they are all equal length.
@example

[1,2,3,4,5,6,7].inGroups(3)         -> [ [1,2,3], [4,5,6], [7] ]
[1,2,3,4,5,6,7].inGroups(3, 'none') -> [ [1,2,3], [4,5,6], [7,'none','none'] ]
