A field that puts allowed users to switch to creative mode within the field.
Either automatic or upon right clicking the block.

Common Sense Constraints for Creative Mode Field:

• Should contain or link in with an inventory switch.
• No items should be able to leak outside the field.
• Upon leaving the field, the world game mode is returned as well as the original inventory
• Upon leaving one & entering another, prevent with some anti-hysterics time filter to prevent the user from taking any action while it all settles into the proper desired state.

New proposed fields:

• inventoryGroup {default | creative | custom} //switch inventory within this field
• autoSwitch true | false //auto switch or manual right click the block?
• noDrop //Kill all drops within the field

Would work well with the a translocator
Would allow puzzle areas to remove all inventory and return the inventory when exiting

noDrop could be nice in an arena like setting, with waves of unrewarded mobs and then receiving a single reward after completing the task.
