###BLOB TRACKER

• ckeck collision between current blobs and list of active blobs
• if blob from active blobs is not colliding with any current blob remove from active blobs list
• if blob from current blobs is not colliding with any active blobs:
• add to active blobs list with new ID
• flag blob for polling
• if blob from active blobs is colliding replace active blob with current blob
• if current blob is colliding with more than one active blob:
• players must be convoluted
• assign current blobs atributes to all active blobs it's colliding with
• flag all active blobs for polling
