Unsure what to do with functions

[ilent2]

Unsure what to do with:

• axial_equilibrium.m
• trapping_landscape.m
• forcetorque.m
• force_z.m

Perhaps other files in +utils package.

[ilent2]

Also, the rotation function probably are no longer needed:

• z_rotation_matrix.m -> rotz(phi)*roty(theta)
• calc_rotation_matrix.m

[AStilg]

I'm for getting rid of z_rotation_matrix in 1.4. Haven't added depreciation warning for it though. I added the warning for calc_rotation_matrix.m

[AStilg]

axial_equilibrium has been there fore a long time as find_axial_equilibrium.m I think it's to keep.

[ilent2]

Resolved.
