fix: null values on ValidatedTomeTopic get

- bind functions on first level attributes
- Do not return data if it is not explicitly set on the data
  (was returning default values)

fix: tome nested deserialization

Methods were not applied properly, and were not callable at runtime.

Fixes #8

stricter type verification on create

fix: strip null values from mget

MAGE's mget implementation does not return the index along
with the data, meaning that values not being found are nulled.
With mage-validator, we return objects with a method to return the
index, and therefore this behavior is not needed.

fix: includes method on ArrayTome

fix: scalar array output validation

@mapof validation function, index/data type check

Added an optional function parameter to @mapof; the goal is
to allow for validation against map keys.

Indexes and `Topic.create` optional data are now type-checked
against the topic index class and the topic class respectively.

@mapof decorator

This commit introduces a new @mapof decorator
for dealing with the deserialization and validation
of key-value maps
