Memory Implementation

# A simple implementation of memory

# Mark:

# Adds a memory address to a watchlist

# Check:

# Checks on all addresses on a watchlist

# If the address has changed state it will report about it

# Write:

# Writes to an address

# Read:

# Returns whatever is at a specific address

#
