* Apex doesn't expose dependent picklist info directly, but it's possible to expose.
* Approach:
*  * Schema.PicklistEntry doesn't expose validFor tokens, but they are there, and can be accessed by serializing to JSON
*    (and then for convenience, deserializing back into an Apex POJO)
*  * validFor tokens are converted from base64 representations (e.g. gAAA) to binary (100000000000000000000)
*    each character corresponds to 6 bits, determined by normal base64 encoding rules.
*  * The binary bits correspond to controlling values that are active - e.g. in the example above, this dependent option
*    is available for the first controlling field only.
