Fixed readme for recents changes
Fixed typo in readme
Remived a few global declarations. Also investigating a bug with CM900A modems and rxpower snmpgets being very slow compared to CM820A
After opening a case with arris, the CM900A at version 7.10.176A resolved the issue of slow response to downstream txpower snmp requests. removed the comment from code after testing it ok.
