Remove “words to avoid in technical writing”

Words were taken from this blog post:
http://css-tricks.com/words-avoid-educational-writing/. It recommends to
avoid using the phrases “obviously”, “basically”, “simply”, “of course”,
“clearly”, “just”, “everyone knows”, “however”, “so” and “easy”. I did a
project-wide search for these phrases and rewrote things where I thought
it improved the sentence.

For future reference, this is the command I ran to find these:

    ag -i '(obviously|basically|simply|of\scourse|clearly|just|everyone\sknows|however|so,|easy)' user
