Camfort.Analysis.LVA

Description

Provides live-variable analysis for Fortran code. One of the simpler analyses in the suite (a good starting point for any new developers). This demonstrates the use of the "zipper" format, and various helpers from Syntax and Traverse.

lva is the top-level definition here.
