AppNexus Bid Adapter : plcmt and startdelay mapping function not returning correct values

Lines 1015 to 1036 in b557f04

	function getContextFromPlcmt(ortbPlcmt, ortbStartDelay) {
	if (!ortbPlcmt) {
	return;
	}
	if (ortbPlcmt === 2) {
	if (!ortbStartDelay) {
	return;
	}
	if (ortbStartDelay === 0) {
	return 'accompanying_content_pre_roll';
	} else if (ortbStartDelay === -1) {
	return 'accompanying_content_mid_roll';
	} else if (ortbStartDelay === -2) {
	return 'accompanying_content_post_roll';
	}
	} else if (ortbPlcmt === 3) {
	return 'interstitial';
	} else if (ortbPlcmt === 4) {
	return 'outstream';
	}
	}

In the getContextFromPlcmt function, when plcmt is 2 and getContextFromPlcmt is 0, it returns out, rather than returning accompanying_content_pre_roll as expected.

That's because (!ortbStartDelay) in line 1021 evaluates to true, so the function just exits. This may need to be (typeof ortbStartDelay !== undefined).

Thanks for reporting this; I'll take a look and put together a fix.
