/**
 * PHP Environment testing
 *
 * There are a few requirements for the PHP environment that this
 * script needs in order to run.  Fatal errors will be output to
 * stderr if this stuff doesn't' work
 *
 * Current sanity checks
 * 1. PHP version (5.4)
 * 2. PHP SAPI (MUST be cli)
 * 3. PHP extensions (spl, date, pcre, reflection and standard)
 * 4. argv/argc
 *
 * Note this file doesn't use namespaces but instead includes the actual run file
 * Should run on any 5+ version of PHP...and bail properly
