Toggle Layer Lock.js

/* Toggle Layer Lock 

Toggles the lock on layers in the active document whose names are specified in the file name.

HOW TO USE:
    - edit this file's name to include the name of the Layers you want to lock, separated by spaces
        NOTE: 
            The layer names are CASE SENSITIVE
        EXAMPLE: 
            My InDesign document has layers named Text, Images, and Guides.
            I want this script to only lock Text and Images, so I rename this file to:
                Toggle Layer Lock Text Images.js
    - run this script normally
