script fails when offsetTop : 0

[ryangall7]

In the checkSettings() method settings[key] evaluates as false when offsetTop is 0.

the whole block of code

  for (var key in settings) {
       console.log(settings[key]);
       if (!settings[key]) {
           errors.push(settings[key]);
       }
  }

seems unnecessary since the only reason a setting would be false is on purpose since the all have defaults.

Yeah - I can confirm this.

Try changing

if (!settings[key]) {

to

if (typeof settings[key] == "undefined") {

because !0 is false - so passing 0 is not allowed - or results in error.

I believe you meant that !0 is true, meaning that it would then flag all non-zero values (including the default) as errors.

Comparing to undefined will fix this one error, but like ryangall7 mentioned, the whole block of code doesn't make much sense. I thought maybe explicitly checking each setting (and giving better error messages than an empty string) was a better way to go, so I submitted a pull request (issue #22) that will hopefully get merged.
