Get the current value for a given field.

This method will coalesce the current request data and the 'defaults'
array.

@param string $field A dot separated path to the field a value
is needed for.
@param array $options Options:
- `default`: Default value to return if no value found in request
data or context record.
- `schemaDefault`: Boolean indicating whether default value from
context's schema should be used if it's not explicitly provided.
@return mixed
Get the current value for a given field .
