Unable to Use Markdown containing code.

Given the following markdown file :

console.log('' == '0');
console.log(0 == '');
console.log(0 == '0');
console.log(false == 'false');
console.log(false == '0');
console.log(false == undefined);
console.log(false == null);
console.log(null == undefined);
console.log(' \t\r\n' == 0);

And the following slide :
`
import equalsSlide from "../assets/equals.md";
...

            <Slide>
                <Markdown source={equalsSlide}/>
            </Slide>

`

The rendered presentation triggers the following error.

marked.js:138 Uncaught TypeError: Cannot read property 'replace' of undefined Please report this to https://github.com/chjj/marked. at Lexer.lex (marked.js:138) at Function.Lexer.lex (marked.js:129) at marked (marked.js:1219) at exec (index.js:184) at Markdown.render (markdown.js:143) at ReactCompositeComponent.js:796 at measureLifeCyclePerf (ReactCompositeComponent.js:75) at ReactCompositeComponentWrapper._renderValidatedComponentWithoutOwnerOrContext (ReactCompositeComponent.js:795) at ReactCompositeComponentWrapper._renderValidatedComponent (ReactCompositeComponent.js:822) at ReactCompositeComponentWrapper.performInitialMount (ReactCompositeComponent.js:362)

I just ran into this with an inline code bit:

Here is a piece of `code`

Slightly different stack, but same error:

Uncaught TypeError: str.replace is not a function

Looking at the devtools, it looks like str is coming in as an array with a single value, the contents of the code. I'm using the MarkdownSlides component in this case.

Great; I tested it and it works just fine!
