Detailed Description

Double the numbers in the first half of a RandomAccessSequence.

5-1. Write a metafunction double_first_half that takes a RandomAccessSequence
     of integral constant wrappers of length N as an argument, and returns a
     copy with the first N/2 elements doubled in value, such that the
     following is true:

     mpl::equal<
         double_first_half< mpl::vector_c<int,1,2,3,4> >::type,
         mpl::vector_c<int,2,4,3,4>
     >::type::value
