beta release of 4.0.0

Many backwards incompatible changes, but they're mostly limited to new stuff, e.g. matrix decompositions, etc.

Improved how Eigen handles zero-matrices

Hipparchus upgrade

Matrix balancing, plus some misc

Reduce the Mockito version

ComplexSchurDecomposition added (large-bulge multi-shift QR algorithm),
Eigen API  added + reworked,
ComplexMatrix data structure optimized, 
Housholder,
ComplexHessenbergDecomposition,
ComplexQRDecomposition,
etc.

Made the Jacobian function specification in the WeightedLeastSquares (and the impl. LevenbergMarquardt) architectures much more clean by simply removing the `dxs` spec. and the derivative spec. in the function classes and making the Jacobian directly specifiable

Added some new methods to better expose the capabilities of DecompositionSolver and pointed the Matrix::solve methods at them (no functional changes),
Added some configurable toString methods to NVector and NPoint

No functionality changes

First proper tag publishing through git

test

Lev.Marq. efficiency improvement (reuse the SVD)

First tag to publish to mvn central, hopefully

First attempt to publish to Maven Central

Updated the build.gradle, next step is adding logic to publish to Maven Central!

Contains initial collection classes, etc. (nearly) as it was used in production.  Changes from production including minor restructuring, class name changes, and re-implementation of methods/classes that are not a part of this project and non-public.

Likely future changes include further restructuring, and class name changes, and new features.
