Stores a string value in a given property.
If no obj parameter is given, then it stores the property on the trigger object. Otherwise, it will store it on the given object.
If you specify a propname that is protected, you will get a Permission Denied error.
You are only allowed to store properties on objects controlled by the owner of the trigger object. The trigger object is the object that triggered the evaluation of the MPI commands.
This function returns the string that is stored as the prop value. If you store a null value in the property, then it will remove the property if it is not a propdir.
It will clear the value of the prop if it IS a propdir.
