role.starter.js

/*
    The starter's role is to go into a room and build it's spawn and level up it's RCL to 2
    
    The starter has the following states: 
        -building : spending resources to build a the spawn
        -fetching : getting resources from the an appropriate source
        -upgrading : upgrading the room controller

    The starter's memory consits of the following:
        -job: the starter's current job
        -work: the room the elf lives in
        -flag: the starter's unique identifier
    
    HOWTO:
        - place a blue flag in the room that says "starter_#"
        -the flag will be removed once the starter has completed their task
    Notes:
        - the elf prioritizes repairs over other jobs
