[WIP] Update timestep values for the new damping module

[bhosale2]

Fixes #118.

The example timestep values will be investigated (with help from @armantekinalp), along with confirmation, that the dynamics of the individual cases stay the same:

• axial stretching - 10x larger timestep, with 10x smaller damping constant
• binder stuff - for snake 12.5x larger timestep, with same damping constant, no change for timoshenko
• butterfly
• continuum flagella - 4x larger timestep, with 4x smaller damping constant
• continuum snake - 12.5x larger timestep, with same damping constant
• Experimental cases - parallel connection - 100x larger timestep, with 10x smaller damping constant
• flexible swinging pendulum
• friction validation cases - 2 times larger time-step, 2 times smaller damping constant
• helical buckling - No improvement.
• joint cases - 5-10x larger timestep, with same damping constant
• muscular flagella - No change. For larger timesteps, it is unstable with the same damping constant
• muscular snake - No change. For larger timesteps, it is unstable with the same damping constant
• restart example
• rod-rod contact cases - 5-10x larger timestep, with 5-10x smaller damping constant
• rod self contact cases - No improvement
• timoshenko - 7x larger tilmestep, with 7x smaller damping constant

LGTM. We can merge, I am excited to see improvements with LaplaceDissipationFilter next.
