Shonan Rotation Averaging.
199 commit messages below, many are obsolete as design has changed quite a bit over time, especially from the earlier period where I thought we only needed SO(4).
* prototyping weighted sampler
* Moved WeightedSampler into its own header
* Random now uses std header <random>.

* ShonanAveragingParameters
* New factor FrobeniusWormholeFactorP computes |Rj*P - Ri*P*Rij|
* Fixed broken GetDimension for Lie groups with variable dimension.
* Removed all but Shonan averaging factor and made everything work with new SOn
* Just a single WormholeFactor, wrapped noise model

* comments/todos
* added timing script
* add script to process ShonanAveraging timing results
* Now producing a CSV file
* Parse csv file and make combined plot
* Fixed range

* roundSolution which replaces projectFrom
* removed extra arguments
* Added to wrapper
* Add SOn to template lists

* give value to xi by block
* correct gradient descent
* correct xi
* }

* Fixed cmake files
* changed sign
* add line search
* unit test for line search
* test real data with line search
* correct comment
* Fix boost::uniform_real
* add save .dat file
* correct test case
* add explanation
* delete redundant cout
* add name to .dat output file
* correct checkR
* add get poses_ in shonan
* add Vector Point type for savig data
* Remove cmake file which magically re-appeared??
* Switched to std random library.
* Prepare Klaus test
* Add klaus3.g2o data.
* fix comment
* Fix derivatives
* Fixed broken GetDimension for Lie groups with variable dimension.
* Fix SOn tests to report correct dimension
* Added tests for Klaus3 data
* Add runWithRandomKlaus test for shonan.
* Finish runWithRandomKlaus unittest.
* Correct datafile.
* Correct the format.
* Added measured and keys methods
* Shonan works on Klaus data
* Create dense versions for wrappers, for testing
* Now store D, Q, and L
* Remove another cmake file incorrectly checked in.
* Found and fixed the bug in ComputeLambda !
* Now using Q in Lambdas calculation, so Lambdas agree with Eriksson18cvpr.
* Make FrobeniusFactor not use deprecated methods
* FrobeniusWormholeFactor takes Rot3 as argument
* Wrapped some more methods.
* Wrapped more methods
* Allow creating and populating BetweenFactorPose3s in python
* New constructors for ShonanAveraging
* add function of get measurements number
* Remove option not to use noise model
* wrap Use nrMeasurements
* Made Logmap a bit more tolerant of slightly degenerate rotations (with trace < -1)
* Allow for Anchor index
* Fix anchor bug
* Change outside view to Rot3 rather than SO3
* Add Lift in SOn class
* Make comet working
* Small fixes
* Delete extra function
* Add SOn::Lift
