Portfolio

Portfolio page produced inline within index.html as hidden span9 in
main row.  Javascript triggered by "view work" link under "#portfolio"
section hides initial span9 with primary sections and replaces it with
portfolio span9.  Initial span given id "homepage" and hidden portfolio
span given id "le_portfolio".

Binding to .nav swaps spans back when any other section link is clicked
from the sidebar-nav, collapse-nav, or .brand links.

When viewing portfolio, selecting a specific item loads that content
from an undisplayed DIV and places it into a div (id "portfolio_stage")
with animate transitions, and also triggers a scrollTop from the
portfolios index at the bottom of the page.

Transitions are animated for webkit compatible browsers.

Portfolio span layout matches PSD spec and is responsive at desktop,
tablet, and phone, per spec design.

Users will only have to copy and past template (coming) div and list
link to create new portfolio items.  Very obvious abd straight-forward
HTML.  (Not present yet, ability to add preview images to portfolio
links).

Added "scroller" script to sidebar-nav (and collapse-nav) which uses
animate(scrollTop) to move between sections.  Rate of transition is
calculated to vary slightly within an acceptable range depending on
distance between sections being transitioned.

demonstration.
