Add tests for markdown support.

Focuses mainly on RML as that's where it will break

+An h1 header
+============
+
+Paragraphs are separated by a blank line.
+
+2nd paragraph. *Italic*, **bold**, and `monospace`. Itemized lists
+look like:
+
+  * this one
+  * that one
+  * the other one
+
+Note that --- not considering the asterisk --- the actual text
+content starts at 4-columns in.
+
+> Block quotes are
+> written like so.
+>
+> They can span multiple paragraphs,
+> if you like.
+
+Use 3 dashes for an em-dash. Use 2 dashes for ranges (ex., "it's all
+in chapters 12--14"). Three dots ... will be converted to an ellipsis.
+Unicode is supported.
+
+
+
+An h2 header
+------------
+
+Here's a numbered list:
+
+ 1. first item
+ 2. second item
+ 3. third item
+
+Note again how the actual text starts at 4 columns in (4 characters
+from the left side). Here's a code sample:
+
+    # Let me re-iterate ...
+    for i in 1 .. 10 { do-something(i) }
+
+As you probably guessed, indented 4 spaces. By the way, instead of
+indenting the block, you can use delimited blocks, if you like:
+
+~~~
+define foobar() {
+    print "Welcome to flavor country!";
+}
+~~~
+
+(which makes copying & pasting easier). You can optionally mark the
+delimited block for Pandoc to syntax highlight it:
+
+~~~python
+import time
+# Quick, count to ten!
+for i in range(10):
+    # (but not *too* quick)
+    time.sleep(0.5)
+    print i
+~~~
+
+
+
+### An h3 header ###
+
+Now a nested list:
+
+ 1. First, get these ingredients:
+
+      * carrots
+      * celery
+      * lentils
+
+ 2. Boil some water.
+
+ 3. Dump everything in the pot and follow
+    this algorithm:
+
+        find wooden spoon
+        uncover pot
+        stir
+        cover pot
+        balance wooden spoon precariously on pot handle
+        wait 10 minutes
+        goto first step (or shut off burner when done)
+
+    Do not bump wooden spoon or it will fall.
+
+Notice again how text always lines up on 4-space indents (including
+that last line which continues item 3 above).
+
+Here's a link to [a website](http://foo.bar). Here's a footnote [^1].
+
+[^1]: Footnote text goes here.
+
+Tables can look like this:
+
+size  material      color
+----  ------------  ------------
+9     leather       brown
+10    hemp canvas   natural
+11    glass         transparent
+
+Table: Shoes, their sizes, and what they're made of
+
+(The above is the caption for the table.) Pandoc also supports
+multi-line tables:
+
+--------  -----------------------
+keyword   text
+--------  -----------------------
+red       Sunsets, apples, and
+          other red or reddish
+          things.
+
+green     Leaves, grass, frogs
+          and other things it's
+          not easy being.
+--------  -----------------------
+
+A horizontal rule follows.
+
+***
+
+Here's a definition list:
+
+apples
+  : Good for making applesauce.
+oranges
+  : Citrus!
+tomatoes
+  : There's no "e" in tomatoe.
+
+Again, text is indented 4 spaces. (Put a blank line between each
+term/definition pair to spread things out more.)
+
+Here's a "line block":
+
+| Line one
+|   Line too
+| Line tree
+
+and images can be specified like so:
+
+![example image](example-image.jpg "An exemplary image")
+
+Inline math equations go in like so: $\omega = d\phi / dt$. Display
+math should get its own line and be put in in double-dollarsigns:
+
+$$I = \int \rho R^{2} dV$$
+
+And note that you can backslash-escape any punctuation characters
+which you wish to be displayed literally, ex.: \`foo\`, \*bar\*, etc.
