Need to fix MATLAB cross-sections to properly use dimensions

[elsevers]

When MATLAB cross-sects have hard-coded coordinates (i.e. the origin), they are using floats instead of a dimensions class. This should be resolved by having the hard-coded coordinates take on the data-type of one of the dimensions variables.

For example, this is the current implementation and it is incorrect
https://github.com/Severson-Group/eMach/blob/4f746ae99e915300cebe542786a76b7eef7387cc/model_obj/crosssects/hollowCylinder/CrossSectHollowCylinder.m#L22-L25

Instead, one should use

x_out = feval(class(t), 0);
x_in = feval(class(t), 0);

All cross-sections need to be checked and updated:

• breadloaf @ngadiyar93
• hollowCylinder @ngadiyar93
• hollowRectangle @ngadiyar93
• innerNotchedRectangle
• inner_rotor_stator
• linearMotorStator
• notchedRectangle
• outerRotor
• outerRotorStator
• parallelogram
• solidRectangle
• trapezoid

Checked arc, breadloaf, hollowCylinder, and hollowRectangle.

arc: No hard coded coordinates.
breadloaf: Fixed in PR #199
hollowCylinder: Fixed in PR #199
hollowRectangle: Fixed in PR #199
