- Implemented `EdgesLengthEqualGoal`.
- Added `AbsoluteError` term.
- Added `MeanAbsoluteError` terms.

Changed

- Fixed omission of `gstate.weight` when computing `PredictionError`.

Added

- Implemented `NotebookViewer` to visualize networks in jupyter notebooks.
- Added `FDNetworkNotebookArtist` to visualize networks in jupyter notebooks.
- Added `noteboks.shapes.Arrow` to display force vectors as meshed arrows.

Changed

Added

- Implemented `NodeTangentAngleGoal`.
- Implemented `NodeNormalAngleGoal`.
- Implemented `NodeTangentAngleConstraint`.
- Implemented `NodeNormalAngleConstraint`.
- Added `EquilibriumStructure.connectivity_faces` to optimize for face-related quantities in an `FDNetwork`.

Changed

- Fixed bug in `edgewidth` sizing in `NetworkArtist` when all edges have the same force.
- Changed `angle_vectors` to return angle in radians by default.
- Shifted loads start point in `plotters.NetworkArtist` for them to be incident to the nodes.

Removed

Added

Changed

- Changed generator unpacking `*sarrays` in `parameters.split` unsupported in Python 3.7.
- Changed tension-compression force color map gradient to a binary color map.

Removed

Added

- Added `goals.NodeZCoordinateGoal`.
- Added `goals.NodeYCoordinateGoal`.
- Added `goals.NodeXCoordinateGoal`.
- Added `constraints.NodeZCoordinateConstraint`.
- Added `constraints.NodeYCoordinateConstraint`.
- Added `constraints.NodeXCoordinateConstraint`.
- Added `IPOPT`, a second-order, constrained optimizer that wraps `cyipopt`, to the repertoire of optimizers.

Changed

- Restructured `optimization.optimizers` into separate files.
- Renamed `goals.edgegoal` submodule to `goals.edge`.
- Renamed `goals.nodegoal` submodule to `goals.node`.
- Renamed `goals.networkgoal` submodule to `goals.network`.
- Enabled support for one-sided bounds in `constraint.Constraints`.
- `NetworkLoadPathGoal` uses `jnp.multiply` instead of multipication operator `*`.
- Broke down `Optimizer.minimize()` into `.problem()` and `.solve()`.
- For efficiency, `SecondOrderOptimizer` calculates `hessian` as `jax.jacfwd(jax.jacrev)`.
- Changed calculation of the scalar ouput of `Loss` using a compact loop.
- Changed calculation of the scalar ouput of `Error` using a compact loop.
