suggest `parseTest` rather than `regularParse`

[danse]

i was following this guide and i rolled out my simplified versions of the parsing help functions you have here. eventually i found out that i just rewrote parseTest.

by suggesting the users to test with parseTest from the beginning you make the guide way easier to follow because we wouldn't need to clone, compile, etcetera

Thanks for the suggestion, I like the sound of it. I want to break it into 2 different ideas:

1. see if it is reasonable to allow people to follow the guide without having to clone it. I never thought about this, but since it (surprisingly) seems like it might be not too much of a change, it's worth looking into

2. using parseTest for all the parsing examples instead of the custom test parsing functions. I think this is a good idea also. I will look into it.
