Add Hope For Healing Guide functionality with Side Nav-bar

[philipye314]

Todo:

• Both the sidebar nav as well as Hope for Healing Guide pages have been merged. Right now, clicking on Hope for Healing will bring you to Charlotte's PR where the nav-bar exists but none of the Hope for Healing Guide pages are being rendered.
• We want the side nav-bar to be able to route to different pages in the Hope for Healing Guide. Keep in mind the Hope For Healing Guide page takes in an ID as a parameter, so we'll have to hardcode the ID's for now.
• Keep in mind that expanding the nav overlays on top of the page shown, so we need to expand/contract the size of the page manually when we open/close the nav.
• This will be a pretty complex PR! Feel free to let me know of any questions that might rise
