Heading seems to fluctuate a lot?

[joachimboggild]

Hi, just found your repo, and it looks very nice :-) I am going a project where I need exactly something like this, and this is a great help.

However, the heading seems to swing a lot: It seems that my heading is completely random to start with, i.e. the POIs entered look correct compared to each other, but if they should be south, they might appear to the east, west and north. Do you know why this is?

I can see that you have a property called debugHeading, how does this help debug the heading?

If you can help me out here, I could help develop the library further - it shows great promise, I think :-)

Sincerely,
Joachim
