This analyzer checks for global variables and errors on any found.

A global variable is a variable declared in package scope and that can be read
and written to by any function within the package. Global variables can cause
side effects which are difficult to keep track of. A code in one function may
change the variables state while another unrelated chunk of code may be
effected by it.
