Create a "yield" and add backwards compatibility for the macro of the
same name. This is one of 2 macros that need to be replaced so we do not
have to worry about them with the new compiler.
This now uses year ranges, which I'll update annually.
This also renames "R-T Specialty" to "Ryan Specialty Group". The latter is
the parent company of the former. I was originally employed under the
former when LoVullo Associates was purchased, by I now work for the parent
company.
Some notes on this: The "Calc DSL" is the name of the DSL before it
became "TAME". This takes the entire core library and squashes its 91
commits into a single one; the reason for this is because those
commits often contain LoVullo-specific details that are either
irrelevant or should not be included.
This library has limited value to the public at the time of this
commit, since TAME has not yet been released (it requires some
additional cleanup and filtering before then). It is also in need of
heavy refactoring and reorganization, since it has accumulated a lot
of cruft, especially since the project in which the Calc DSL was
introduced was rushed (to put it lightly). Forgive the mess.
[LoVullo employees: the commit was extracted from dsl.git 4a3aea9;
full history can be found there. This commit contains some additional
minor tweaks in addition to squashing. It filters on the :/core/
directory.]
