somehow, in certain cases, I was unable to generate a trajectory without getting an error that the operator / can't work between list (omgmat) and float... so changing that fixed it for me.
+ Fixed some spelling mistakes
+ Cleaned up tab/space indentation. Previously some of the samples would not
work if copied/pasted into a Python interpreter because of mixed tabs/spaces
+ Cleared all trailing whitespace
+ Missing quotation marks in some sample code caused mistakes with printing
messages
+ Added all import statements to some of the examples that already had some
import statements
