As a games developer
I would like to be able to access a map of virtual keys
So that I can:

• Quickly detect whether a specified key is down or up
• Detect more than one key press at a time
  And for those keystates to be managed automatically by the MOS

Acceptance Criteria:

• Keystates to be stored in a compact format (bit-packed)
• API calls for:
  • Getting the address of the keymap structure
  • Detecting whether a given key is pressed or not
