Julian Kent 368a738e52 AutoDiffCostFunction: optional ownership 
Add Ownership semantics to the AutoDiffCostFunction

This allows several benefits, such as pointer ordering always being the
same for numerical repeatability (due to blocks being ordered by
pointer address), memory adjacency for better cache performance, and
reduced allocator pressure / overhead.

This is then made use of in libmv by preallocating the errors and
cost functions into vectors

Doing this also necessitated some re-organization of the derivatives
article into chapters and some minor edits.
