Create ranges

[swo]

People really like linspace and aspace. In an updated schema (see #30 ), have some special keys like _linspace or something, that trigger the generation of ranges

See #55 (comment)

If you make a range from 0 to 1, and then try to get 0.5, will you actually hit that value?

I think there's a way this could fit unambiguously into this schema: eg R0: {vary: [1.5, 2.5]} and then R0: {vary: {range: {from: 0.0, to: 1.0, n: 11}}}. i.e., if the thing after vary: is an array, use those values, but if it's a dict, then it needs to be a dict that makes some other kind of specification, like range

For even more clarity, this could be that we have a verbose form:

my_bundle:
  vary:
    my_param:
      values: [value1, value2]

which has the familiar short form:

my_param:
  vary:
    [value1, value]

but that also allows for different things like ranges:

my_param:
  vary:
    range:
      from: 0.0
      to: 1.0
      n: 10
