Cary R d6b6b76015 Update header files to use a more standard name to prevent rereading 
This is from github report #16. There are likely a few more issues
that need to be addressed though this takes care of the major ones.

Stephen Williams d9fea802da Function declarations in packages 
This is still basic. Definitions are still not done.

Stephen Williams 3e419dc854 Parse/decorate sequential statements. 
Get to the point where our sample program parses completely, and
the sequential statements generate SequentialStmt objects and a
process object in the architecture.

Also add a few missing expression types.

Stephen Williams f61428dc82 Basic elaboration of vhdl component instantiations. 
This gets us as far as emiting a component instantiation. Very little
error checking/elaboration is done, so there is room for improvement,
but this is a working stub.

Stephen Williams f32ede23b7 Do type mapping in the parser. 
In VHDL, types are declared before they are used, so it is possible
to do type binding during parse. This makes the parser a little bit
cleaner.

Stephen Williams 769159d053 Add parse decorations for expressions. 
Elaboration will need a parse tree for expressions. Create one for
the expression types that are currently supported. Also add rules
and the keywords for all the remaining binary logical operators.
