octave: liboctave/array/Array.h annotate

annotate liboctave/array/Array.h @ 23420:1fee389bd04b

Use std::copy_n rather than std::copy for clarity in liboctave/array. * Array.cc, Array.h, Sparse.cc, Sparse.h, boolSparse.cc, idx-vector.cc, idx-vector.h: Use std::copy_n rather than std::copy when clarity of code would be improved.
