[sr-dev] htable add/delete RPC commands

[Ovidiu Sas]

Hello Daniel,

The readme file or the cookboks don't say anything about this.
Can you please enhance the readme?
 - the indexing: key_name[n]
 - the array size: key_name::size

Question: can the following syntax be used to delete a specific
element in an array key?
kamcmd htable.get students anna[2]
kamcmd htable.get students anna[0]

Regards,
Ovidiu Sas
