os.freemem() to see how much physical memory is free

os.totalMem() to see the total

calculate cpu usage using os.cpus()

• command-line for polling frequency (default to one second)
• subtract all current values from prior values to get delta-since-last-check
• calculate load by adding all values and dividing that by idle time values
  • it might be that we need to use (total - idle/total)

Components to make:

• PercentBar
• PercentValue
• ScrollingGraph
• DateLabel
• TimeLabel
• DateTimeLabel
