looking at it again, I think we need to be a bit careful, it seems there 
is a possibility that None could get passed to save_array

we pass out_folder and dict to read_ms_markdown but filename is gleaned 
from the input html

so... for the above it is possible that save_array could be called with 
None, maybe this should be an error ?

Or we could always create a temp out_dict at the top of 
read_ms_markdown. I don't think it makes sense to default out_dict in 
save_array (and passing None to save_array *should* be an error and fail 
imo) Thoughts ?
