Addresses UK-170 [CD1]

One of goals of C++0x is to make language easier to teach and for 'incidental' programmers. The fine-grained headers of the C++ library are valuable in large scale systems for managing dependencies and optimising build times, but overcomplicated for simple development and tutorials. Add additional headers to support the whole library through a single include statement.

> We do not all agree that this is an issue, but we agree that if it needs solving this is the right way to do it. Move to Tentatively Ready.

[ 2009-07-06 Beman notes: ]

> This issue adds a header `<std>`.

> There is a paper to be looked at, N2905 Aggregation headers, that adds a header `<std-all>` that is the same thing except it excludes deprecated headers. N2905 also proposes a second aggregation header.

> Seems like this issue should be held in abeyance until the LWG has had a chance to look at N2905.

> No consensus for change.

Proposed resolution:

Insert a new paragraph in 16.4.2.3 [headers] between p4 and p5

> An additional header `<std>` shall have the effect of supplying the entire standard library. [Note: for example, it might be implemented as a file with an `#include` statement for each of the headers listed in tables 13 and 14. -- end note]
