Cascade Outline Number of Headings

The headings notation 'hn.' are only renderred in different font size, which would be vague sometimes in a complex content. The Cascade Outline Numbers of Heading make content clearer. A new wiki notation should be introduced, such as 'h#n.', in order to render a cascade number. Moreover, while displaying a page included other pages, the cascade numbers in the included pages are adjusted automatedly.

for examples

h#1. Heading-1
h#2. Heading-2
h#2. Heading-3
h#1. Heading-4

to be renderred:

1. Heading-1
1.1. Heading-2
1.2. Heading-3
2. Heading-4
