check for jQuery by looking for $ might cause conflicts

[timelyportfolio]

I discovered this as I explored #83. In lines and lines of events, there is a check to see if jQuery is present by looking for $. I learned that the Chrome command-line API also defines a $ which causes $ to not be undefined when running from the console and the subsequent $(plotObj) to fail. I am aware of some other libraries that hijack the $. Would if( typeof jQuery !== undefined) be a more robust test? Or should $(plotObj) be wrapped in a try?

If nothing else, filing (and closing) this issue might help someone else in the future who might be trying to debug this problem.

Interesting. if( typeof jQuery !== undefined) does sound more robust.

Filling this as a bug.
