/**
* 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.
