Headers

Each header creates a new heading block. To refer to the block #Heading name, use the syntax _"heading name"

Capitalization does not matter. Internal spaces probably matter, but the end spaces do not matter. Number signs at the end of a heading are ignored.

One can also use the underline syntax to create a heading.

The link directive can also be embedded in a header. The primary use of this is to have a version number at the top heading such as # [Factorial](# "Version: 0.1.0")

Headers should be unique. If they are not, then subsequent headers have an increment added on. For example, if #Great Title appears 3 times, then the sections, in order of appearance of the document, become equivalent to Great Title, Great Title 1, and Great Title 2. A warning is issued under verbose compiling of repeated headers.
