Centralize configuration values

Consolidate all configuration variables, constants, and settings into a centralized configuration object rather than declaring them as scattered variables throughout the codebase. This improves maintainability, reduces duplication, and enables consistent templating patterns.

Instead of defining variables separately:

var cTestClean, cTestCompile, cTestExecute;
var pathDelimiter = path.delimiter;

Add them to your config object:

var config = {
  libName: 'css-layout',
  distFolder: 'dist',
  srcFolder: 'src',
  cTestClean: '...',
  cTestCompile: '...',
  cTestExecute: '...',
  pathDelimiter: path.delimiter
};

This allows for consistent templating usage like <%= config.pathDelimiter %> instead of mixing template strings with concatenation, and keeps all configuration in one discoverable location.
