Ok, so using the debug tools, I can print out the tab using console.log
(), but when I try to assign to local variables, they do not get
changed at all.
var t = null;
chrome.tabs.getSelected(null, function(tab){
t = tab;
console.log(tab);});
When it runs, the console will have a correct trace, but t will still
be null.
