Structure of certain settings to make them easier to read

[dgupta7]

There are some settings like S.bounds.coordinates, S.misc.msk_geom_bounds, S.subject.muscle_strength, S.subject.muscle_pass_stiff_scale, S.subject.muscle_pass_stiff_shift, S.subject.tendon_stiff_scale, S.subject.scale_MT_params, S.subject.set_damping_coefficient_selected_dofs, S.subject.set_stiffness_coefficient_selected_dofs whose structure can be changed and made easier to use and read.
Currently these settings are cell arrays of size [1 x 3*no of settings]. For example, For example, S.subject.scale_MT_params = {{'soleus_l','soleus_r'},'FMo',0.9,{'tib_ant_l'},'lTs',1.1} will scale max isometric force of both soleus by a factor of 0.9 and tendon slack length of tibialis anterior left by a scale of 1.1.
I think we should change the structure to have a size [no of settings x 3]. So for the above example,
S.subject.scale_MT_params = {{'soleus_l','soleus_r'},'FMo',0.9;...
{'tib_ant_l'},'lTs',1.1}
This way, when a reader reads the settings in the variables window, the changes appear in separate rows, rather than all lumped one after the other in the same row.
