/**
* Get or inject a MAB API variable
*
* 1. As a getter (option 1):
* ==========================
* Usage: $this->MAB('name'); // name is an API variable name
* If 'name' does not exist, a WireException will be thrown.
*
* 2. As a getter (option 2):
* ==========================
* Usage: $this->MAB()->name; // name is an API variable name
* Null will be returned if API var does not exist (no Exception thrown).
*
* 3. As a setter:
* ===============
* $this->MAB('name', $value);
* $this->MAB('name', $value, true); // lock the API variable so nothing else can overwrite it
* $this->MAB()->set('name', $value);
* $this->MAB()->set('name', $value, true); // lock the API variable so nothing else can overwrite it
*
* @param string $name Name of API variable to retrieve, set, or omit to retrieve the master ProcessWire object
* @param null|mixed $value Value to set if using this as a setter, otherwise omit.
* @param bool $lock When using as a setter, specify true if you want to lock the value from future changes (default=false)
* @return mixed|ProcessWire
* @throws WireException
*
