Started on HessianFactor, converted Nonlinear stuff and disabled a lot of more advanced classes so the library compiles with nonlinear using unordered.

Fixed iSAM2 bug where assignment operator and copy constructor may cause null pointer exception when trying to clone cached linear factors, which become null by calling marginalizeLeaves with linear factor caching enabled.

Added optional iSAM2 parameter that forces extra keys into the re-eliminated set. This can be used to force certain keys to be re-ordered.

Fixed bugs in iSAM2 leaf marginalization found in HMF testing - set of factors to remove, adding new leaf clique from remaining variables. Also relies on bug fix in BayesTree::removeClique a couple of commits ago.

Maintain reverse-lookup inside of Ordering, to allow fast partial permutations, and modified iSAM2 to use partial permutations on Ordering. Removed InvertedOrdering and updated other GTSAM code and unit tests to use the Ordering reverse-lookup function "key" instead of calculating and inverse ordering.

For speed, added partial permutation version of VectorValues::permuteInPlace and removed Permutation::partialPermutation (which generated a full-length permutation with only a few entries rearranged)

In iSAM2, added a check in the Batch-mode path that checks if linearized factors should be stored for performance reasons. Without this, factors were cached in batch-mode but not in the normal incremental-mode, leading to inconsistency

Moved the 'markKeys' generation in iSAM2 until after the call to RemoveVariables. Since the 'RemoveVariables' function permutes the ordering, this ensures markedKeys uses the correct indices

Added yet another configuration parameter to iSAM2. 'enablePartialRelinearizationCheck' checks variables for relinearization by descending the Bayes tree. Once a variable does not need to be relinearized, we stop checking that branch. A full check is still the default.
