/** 
 *  Do an SNMP Set based on command line arguments. 
 *  Since variable type and strings to the correct variable type,
 *	are got from the command line args itself,  the
 *  MIB corresponding to any object need not be loaded.
 *
 * [-d]                - Debug output. By default off.
 * [-c] <community>    - community String. By default "public".
 * [-p] <port>         - remote port no. By default 161.
 * [-t] <Timeout>      - Timeout. By default 5000ms.
 * [-r] <Retries>      - Retries. By default 0.
 * [-v] <version>      - version(v1 / v2 / v3). By default v1.
 * [-u] <username>     - The v3 principal/userName
 * [-a] <autProtocol>  - The authProtocol(MD5/SHA). Mandatory if authPassword is specified
 * [-w] <authPassword> - The authentication password.
 * [-s] <privPassword> - The privacy protocol password. Must be accompanied with auth password and authProtocol fields.
 * [-n] <contextName>  - The snmpv3 contextName to be used.
 * [-i] <contextID>    - The snmpv3 contextID to be used.
 * [-pp] <privProtocol> - The privacy protocol. Must be accompanied with auth,priv password and authProtocol fields.
 * <host> Mandatory    - The RemoteHost (agent).Format (string without double qoutes/IpAddress).
 * <type> Mandatory    - Object Type.
 * <OID>  Mandatory    - Give multiple no. of Object Identifiers.
 * <value> Mandatory   - the values of the specified data type.
