/**
 * The Conflicter is a module that can be used to detect conflict between files. Each
 * Generator file system helpers pass files through this module to make sure they don't
 * break a user file.
 *
 * When a potential conflict is detected, we prompt the user and ask them for
 * confirmation before proceeding with the actual write.
 *
 * @constructor
 * @property {Boolean} force - same as the constructor argument
 *
 * @param  {TerminalAdapter} adapter - The generator adapter
 * @param  {Object} options - Conflicter options
 * @param  {Boolean} [options.force=false] - When set to true, we won't check for conflict. (the conflicter become a passthrough)
 * @param  {Boolean} [options.bail=false] - When set to true, we will abort on first conflict. (used for testing reproducibility)
 * @param  {Boolean} [options.ignoreWhitespace=false] - When set to true, whitespace changes should not generate a conflict.
 * @param  {Boolean} [options.regenerate=false] - When set to true, identical files should be written to disc.
 * @param  {Boolean} [options.dryRun=false] - When set to true, no write operation will be executed.
 * @param  {Boolean} [options.cwd=process.cwd()] - Path to be used as reference for relative path.
 * @param  {string} cwd - Set cwd for relative logs.
