e61b406547 OPA conformance (#71)
- Remove unnecessary memory allocations
- Add --non-strict flag
- Ensure that only empty modules (ones without rules) are initialzed prior to evaluating rules.
- Record rule as entry for each of its prefixes.
  For example, for a rule a.b.c =... in package test, record it in
  rules["data.test.a"], rules["data.test.a.b"] and rules["data.test.a.b.c"]

  This allows evaluating the correct list of rules based on expessions
  a.b.c, a.b, a, data.test.a.b.c, data.test.a.b, data.test.a

Closes #69
Closes #70

3514594c56 Use Rc<str> instead of string. (#52)
This reduces std::mem::size_of::<Value>() to 16 bytes.
String values are also efficiently copied like Objects, arrays, sets etc.

When multiple function rules are evaluated, ensure that constant argument values
match before running the rule. If actual parameter does not match the constant parameter,
then the rule is skipped.

72070a7061 Avoid dependency on `source lifetime. (#43)
This allows holding onto objects, caching results etc easily.
However it does introduce the overhead of ref counting.
