What are the configure options mean?

[khsjh]

I'm so glad to know Higashi and Fast-Higashi.
But I can't run this tools because I don't know argument of configure.json file
There are any information about configure in github.
Also in Higashi article, there are some information of configure and almost of all didn't described (as I view)

Is there any default value and the reason in test configure file?
I want to know what the "-1" value means (False?) and why you set some resolution, distance and other values.
I want to see all the explanations for my greed, but if it's difficult, I want to know about the main options

And in Fast-Higashi, there is "vis_palette" option.
Is it right that it can be used when I know what clusters exist?
Then, is it impossible using this option in Higashi?
