7a74137904 MATH-863 
New "Quaternion" class. Thanks to Julien Anxionnat.
After applying the original patch, the following changes were made:
* Renamed the "static" quaternion instances ("PLUS_" prefix removed).
* Removed some (syntactic sugar) methods; removed or modified corresponding
  unit tests.
* Made the redundant accessors call the "canonic" ones.
* Removed the default tolerance and added an explicit tolerance parameter
  in methods that depend on equality testing.
* When a "ZeroException" is thrown, the actual value of the norm is provided
  in the detailed message (as the implementation actually does not use a
  strict comparison with 0).
* Added "equals(Object)" and "hashCode" methods.
* Javadoc and formatting. Added license header.
* Removed "toString" documentation (as this representation should not be
  binding). Changed the representation to not use a comma.
* Renamed "scalarMultiply" to "multiply".
* More stringent tolerance used in the unit tests assertions, whenever
  possible.
* Added unit tests.

87b597c622 Added a new package dealing with differentials. 
The package is intended to deals with one or more free parameters and
derivation order 1 or higher.

The core elements are based on Dan Kalman paper "Recursive Multivariate
Automatic Differentiation", Mathematics Magazine, vol. 75, no. 3, June
2002. For efficiency, the recursive structure is compiled as simple
loops once for each pair (number of free parameters, derivation order).

This is work in progress, there are still some features missing even in
the most basic blocks (typically the asin, acos, atan, atant2 and taylor
methods in DSCompiler). There are also still no high level
differentiator implementation.
