Simple script that finds all files with lodash 3.x method calls within a given directory so you can upgrade them to lodash 4.x

lodash-4-migrate

# Use to find methods that were renamed in lodash 4. https://github.com/lodash/lodash/wiki/Deprecations
# Ex: `./lodash-4-migrate.sh src/` to find files that contain any of the lodash 3.x names in the src/ directory.
# supporting the _.chain() methods such as .min() can produce false positives such as Math.min(). See line ~151.
