Updates to slider range, constrainValue

[arouinfar]

This stems from #147, but is a general design change so creating a separate issue.

Amplitude:

• [x] Increase range to 1.3 cm
• [x] Use constrainValue to snap thumb in steps of 0.1 cm

Frequency:

• [x] Use constrainValue to snap thumb in steps of 0.1 Hz

Pulse Width:

• [x] Use constrainValue to snap thumb in steps of 0.1 s

Damping:

• [x] Use constrainValue to snap thumb in steps of 5%

Should be implemented in the above commit, can you verify?

@jonathanolson the ranges and thumb snapping looks good in master, but the tweaker increment should still be the smallest possible step size.

• [x] Amplitude: 0.01 cm
• [x] Frequency: 0.01 Hz
• [x] Pulse Width: 0.01 s
• [x] Damping: 1%
• [x] Tension: 1%

I believe that should be fixed, apologies! NumberControl is generally set up to use the same step sizes for the buttons and slider.

Looks great, thanks @jonathanolson!
