less, head,tail of Union(AbstractMatrix,AbstractVector)
Example:
julia> a = rand(3,3)
3x3 Array{Float64,2}:
0.766276 0.0889738 0.766481
0.462892 0.373601 0.519861
0.106218 0.143746 0.93921
julia> less(a)
0.766275719445157 0.088973818257575 0.766481334416224
0.46289191095778826 0.3736013900788684 0.5198610738240492
0.10621829502292024 0.14374570106101703 0.9392096208934924

Some similar macros to intercept STDOUT of a program (@stdohless, @stdohead, @stdotail)
Example:
julia> @stdohless 3 for i=1.:1.:100000. println(i) end;
1.0
2.0
3.0
It somehow overwrites the builtin pager behavior, so that once included,
julia> println |> less
does not work anylonger. TO BE FIXED.
