Document block-level evaluation of LossFunction

Note in LossFunction::Evaluate docs that s = ||f_i||^2 is the squared norm of the entire residual block rather than its individual scalar components, and add a modeling FAQ explaining why independent measurements should be placed in separate ResidualBlocks when using a LossFunction.

Fixes https://github.com/ceres-solver/ceres-solver/issues/264

Ceres Solver

Ceres Solver is an open source C++ library for modeling and solving large, complicated optimization problems. It is a feature rich, mature and performant library which has been used in production at Google since 2010. Ceres Solver can solve two kinds of problems.

  1. Non-linear Least Squares problems with bounds constraints.
  2. General unconstrained optimization problems.

Please see ceres-solver.org for more information.
