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.

This allows holding onto objects, caching results etc easily.
However it does introduce the overhead of ref counting.

1. Numeric indices will be converted to strings for refs beginning with `data`
if there is not valid numeric key
2. Error out if input document already contains value for a ref

1. Skip recording undefined variables
2. Parse `in` correctly if it is not imported.
3. base64.decode
4. Handle `with` modifier for qualified data and input.

Expressions are scheduled based on dependencies and thusthe gathered
expression values may not be in the same order as in source.
Reorder to match the source.

When evaluating rules, upon error the last pushed scope wasn't being
popped from the stack of scopes. This causes incorrect behavior
when there are multiple definitions for the same rule name.
The fix is to make sure that the scopes are popped manually upon encountering errors.
Once the interpreter logic is locked down, then we need to clean up scope management
using Drop functions so that the cleanup happens even during short circuited return.

Rename compare.rs to comparison.rs to match OPA documentation of builtins.
Also update loop handling to ensure that the current scope is restored after
each iteration of the loop so as to undo side effects of the iteration.

Support "var = value", "value = var", and "var = var"
Fall back the '=' to comparsion when both operators are defined
Correctly support variable shadowing with "var := value"
Also, remove the unused Variable struct

Only scalars, composites and comprehensions containing scalars are supported.
This will be changed as OPA fixes bug with default values
