[lmi] How logic-less is mustache?

[Greg Chicares]

I'm guessing that mustache templates are _absolutely_ "logic-less".
It's just a little surprising to see, e.g.,
  {{^StateIsNewYork}}
when we already know the state and only want to compare it to "NY"; or
      Separate Account: 
{{GenAcctAllocationComplementPercent}}<br>☜
  &nbsp;&nbsp;&nbsp;&nbsp;Guaranteed Principal Account (GPA): 
{{GenAcctAllocationPercent}}<br>☜
where one variable is just 100% minus the other, especially in light of
the way I initially read mustache's "Hello, world!" equivalent:

| A typical Mustache template:
|
| Hello {{name}}
| You have just won {{value}} dollars!
| {{#in_ca}}
| Well, {{taxed_value}} dollars, after taxes.
| {{/in_ca}}
| Given the following hash:
|
| {
|   "name": "Chris",
|   "value": 10000,
|   "taxed_value": 10000 - (10000 * 0.4),
|   "in_ca": true
| }

I mean, we can do arithmetic:
|   "taxed_value": 10000 - (10000 * 0.4),
but that's input provided to mustache, rather than mustache code, right?

Mustache has 'lambdas', but they aren't a back door through which
we can introduce, e.g., a "complement" function like:
  (lambda (x) (- 1 x))

I'm sure this is all by design. It's just startling that we need to
define a "StateIsNewYork" variable.
