I created a "LineDelay" and a separate "penDelay."  The "LineDelay" is because I found the 'bot wouldn't wait until it finished a line before moving on to the next command - causing it to round off corners.  The "penDelay" (yes, I know I'm doing inconsistent camelCase - I'm planning to fix this soon) was just some of my shape drawing functions that shouldn't be included here anyhow.
