tidy up

[rob-hamill]

• EquilibriumGapMetric(IMetric):

• SliceWiseSpatialParameterisation(ISpatialParameterisation):

• SliceWiseForceReconstructionMetric(IMetric):

• remove @Property use

• test case for normalisation

• Objective functions

  • function first names

• SliceMetricType = SliceWiseForceReconstructionMetric

• refinement.py

  • from typing import TYPE_CHECKING, Literal
  • if TYPE_CHECKING: from pyvale.vfm.identification import PhaseRuntime

• move refinement implementatiosn to their own file (refinement.py can just define interfaces)

• rename SliceMergeSplitRefinement(IRefinementPolicy) to RefinementSliceMergeSplit

• remove propose and just have actions to simplify

• aliases:

  • `SlicePartition = SliceAreaPartition
  • build_slice_partition = build_slice_area_partition

• SlicewiseSpatialParameterisation = SliceWiseSpatialParameterisation

• basis functions review

• is equivalent to fucntion

• validation in vfmesh.py

• def _fill_missing_1d_axis(#def _structured_coordinate_grid_from_measurements( in vfmesh.py

• is x and y uniform grid?
