Security names returned by lookupSecurity

[joshuaulrich]

I was surprised that the security names returned by lookupSecurity() could not be passed directly to another Rblpapi function, like bdh(). I haven't looked at the code to understand where those values come from, though I suspect they're simply passed-through from whatever the API function returns.

So I'm soliciting feedback for the best way to achieve what I want. The options I can think of off the top of my head:

1. Modify lookupSecurity() to return security names that can be used in other functions
2. Add a translator function

I was also surprised that the yellowkey values were not consistent with what needs to be used when specifying a security name. Support for that could be added without changing the current defaults.

All of those would strike me as API issues we cannot do much about given the famously opaque documentation. But if you can come up with workarounds, let us know.

@joshuaulrich you could try an approach like the regex referred to in #215 (comment). You may need to modify to your exact requirements.
