found bug where model mesh was being transformed to print bed centre, but stress data was not shifted with it. need to fix

update cost function for given indices inplace (no longer copies slice from dataframe and reassigns)

stress aligned layers now start warping from previous layer. Cost function is evaluated from surface normals. Stress field needs smoothing big time

read in p stresses, evaluate cost function and store as scalar field on model mesh. set up repo for stress aligned work.

add rounding method for mcode dataclasses. Add useful display info for optimisation, adjust optimisation limits
