Implementation of ThParty
|Need an NB return on failure|
myExt is used as Intelnet authorization code.

Return the Rname for a given party
|Need NB indicating why null handle returned.|
Party does not already exist.  Make one if possible.
Get data base information
By this time, assume upstream processes have validated, authenticated the rName
Telephone system extension
Party does not already exist.  Make one if possible.
Doesn't handle oldHandle (ReRegister) yet.
Implementation of ThPartyPrivate
|Need NB why failed|
Doesn't handle oldHandle (ReRegister) yet.
|Need NB why failed|
Allow only one Manager. Allow it to be the new one.
Take care of encryption, and talking to calling smarts
Create Smarts body, link with Party; we're rolling.
Remove party from each conversation in which smarts is the voiceSmarts, or to which no enabled smarts remain connected.  Outside loop avoids Foreach/Erase conflicts.
Party is serving no smarts; destroy the party itself.

Discussion:
The idea is that as Smarts register with a Party they are connected by links whose attributes are derived from their properties and degree of authentication.
When Parties initiate actions that involve Smarts they will select the Smarts to respond in an order determined by the attributes, including SmartsRole, authentication (maybe, see notes), etc.
Each kind of Smarts has its own link name to its Party
A Manager also needs to know the party to whom the physical workstation belongs, as an aid to locating the corresponding voice terminal.  Set up the relationship, then locate the adjacent terminal, if one already exists.
When the Manager registers first, the $Adjacent link must be sent when the Lark smarts arrives or dies and revives.
A Manager also needs to know the party to whom the physical workstation belongs, as an aid to locating the corresponding voice terminal.  Set up the relationship, then locate the adjacent terminal, if one already exists.


See if it works just to get the first instance of the highest priority connection that exists,
using standardPriorities.
