MrDox Fails to Generate Documents if Output Directory Doesn't Exist

[fpelliccioni]

Description:

When using the --output=<DIR> option with MrDox, the specified <DIR> directory must pre-exist; otherwise, MrDox doesn't generate any documents nor reports errors or warnings to the user.

Steps to Reproduce:

Run MrDox with the --output=<DIR> option where <DIR> is a directory that does not exist. Observe that MrDox does not produce documents and does not alert the user that <DIR> needs to pre-exist.

Expected Result:

MrDox should either create the <DIR> directory if it doesn't exist, or MrDox should inform the user with an error or warning message indicating that the <DIR> directory does not exist.

Actual Result:

MrDox does not generate documents and provides no feedback to the user regarding the output directory issue.
