/**
 * PHP_CodeSniffer tokenises PHP code and detects violations of a
 * defined set of coding standards.
 *
 * Standards are specified by classes that implement the PHP_CodeSniffer_Sniff
 * interface. A sniff registers what token types it wishes to listen for, then
 * PHP_CodeSniffer encounters that token, the sniff is invoked and passed
 * information about where the token was found in the stack, and the token stack
 * itself.
 *
 * Sniff files and their containing class must be prefixed with Sniff, and
 * have an extension of .php.
 *
 * Multiple PHP_CodeSniffer operations can be performed by re-calling the
 * process function with different parameters.
