formatting/typos

[matthewlee01]

hi! a couple formatting/spacing problems i noticed in EssayBody:

line 50: missing . in ellipsis (.. instead of . . .)
lines 211/213: should be double quotes
line 352: missing {" "} at end of line
line 497: grammatically 'e.g.' should be 'i.e.'
line 624: missing {" "} at end of line
line 673: missing {" "} at end of line
line 674: missing . in ellipsis (.. instead of . . .)

i have these suggestions already changed on a local branch if you're open to me pushing a PR, otherwise hope this helps :)
really enjoyed this project!
