Adjusted link hover css of primary panel headings so there is no underline instead text gets darker. Also added the .collapse-chevron class to automatically switch between .glyphicon-chevron-up and .glyphicon-chevron-down depending on whether or not the panel is collapsed.
changed .collapse-chevron font size to 12px
Added a margin to the right of .collapse-chevron
Added a border to the pills navbar.
Created the collapsable panel framework for the help section.
