An attempt to have a "rational" whos() (ala matlab) function in python that only displays variables set in the script (e.g. not the sausage in matplotlib and numpy). More for seeing what variables are rather than debugging. Great for working thermodynamics problems.

This examines the file for variable assignment, and then cross references that assignment with the local variable space. If there's a match the variable is printed.

This is probably exceptionally unstable, but it's worked the last 1000 times I've run it.
