Suggection: add the hidden file system attribute to .baseDir.ts files so they arent' visible.

.baseDir.ts is obviously a hack that litters the code base, if there is no better way to overcome the problem please at least make this file invisible by utilizing an appropriate file attribute of the file system

I can implement this if others are in agreement. I don't know enough about why .baseDir.ts is required to know if this is a good idea or not.

@nycdotnet this explains why it is required : #77

Feel free to implement modifying the file property. Its a very safe change 👍
