Refined template logic
	Modified how version description is displayed to prevent unusual formatting from occuring (due to escaping newlines for HTML parsing)
	Moved Type class into its own file.
	Modified mustache templates to reflect logic changes.
	Changed main procedure to generate both changelogs in one run (rather than having to rerun the program).
	Further enhanced test case to incorporate a full run of the program (both changelogs).
	Added --changelog-file-name parameter to allow users to specify the path and file to save the file-level changelog to.
	Opened a few accessor functions to allow access to values for test case assertions.
	Added sample changelog file.
