Closes #346

This is an improvement over #347

This pull request adds the feature of markdown shortcuts for headings. Now we can insert headings in the document with the help of just the #.

• # => H1
• ## => H2
• ### => H3
• #### => H4
• ##### => H5
• ######=> H6
• ---, - - -, **, => PageBreak

• This is a refactor to the #347 which was suggested by @dselman here.
• I could be wrong in understanding what Dan was saying. I want to get the opinions of Dan and other mentors on how to implement the structure for the matchCases so it becomes very easy to implement more matching functions later in the future.

Changes

• A file called `matchCases` is added inside the `utilities` folder. This file is supposed to contain all the upcoming match cases that would be added i.e. code block, ordered and unordered lists, bold, italics etc.
• A bug in the existing page break shortcut was fixed where it would keep the line where we inserted the ---.
