Hi, While trying to install jaeger, I ran multiple times on this error ``` Exception has occurred. Error: Call to undefined function OpenCensus\Trace\Exporter\Jaeger\gmp_add() ``` I think it will be nice to add to the README a word about needing to install [GMP](http://php.net/manual/en/gmp.installation.php). Anyway thanks for your work and your contributions and if you agree, I can submit a small pull requests for the README.
