Ranges should support min/max with more than 2 decimals.

Stuart: Range setting sliders don't behave well for the case of specifying a small
part of the range from min to max. That is if a variable has a range from
0 to 1, but what we're interested in is looking in detail at 0.0001 steps
from 0.0012 to 0.0022, then it is very difficult to set 0.0012 and 0.0022.

LD: In think you are referring here at the ability to change this value from keyboard arrows
Noted, but this is low priority.

SK: The arrows thing is an issue too, but here I'm referring to the ability to
set a range significantly different to the complete one. To see this, as an arbitrary example, try and set the parameter 'a' for FitzHughNagumo to have a range from 1.0001 to 1.0002 (the specific example is contrived, but the basic specificity is required). Marmaduke's comment about having text field for high and low of the range would be one solution.

LD2: Currently the min and max values for the range seems to work with 2 decimals only.
We should be able to extend this (support a variable number of decimals, based on default ranges, or on a traited field).
I would more than gladly take Marmaduke's suggestion, but the option with having text fields for high and low is not really an option, as when we had the requirements specified for a range, the UI control was one of them. I specifically remember there was a drawing of it. :-|
