A function that takes a variable name as a parameter and
returns an Option[String] value for the variable,
or None if there is no value
(Map[String, String].get(), for instance).
true for a "safe" template that just substitutes
a blank string for an unknown variable, false
for one that throws an exception.

Replace all variable references in the given string.
Replace all variable references in the given string. Variable references are recognized per the regular expression passed to the constructor. If a referenced variable is not found in the resolver, this method either:
- throws a VariableNotFoundException (if safe is false), or
- substitutes an empty string (if safe is true)
Recursive references are supported (but beware of infinite recursion).

Right(substitutedValue) or Left(error)
A simple, configurable string template that substitutes variable references within a string.
