[Cppqed-support] new tcc include scheme

[Raimar S. <rai...@ui...>]

Dear András,

I have pushed raimar/tcc_new (and removed raimar/tcc). Tcc_new is already 
branched from the latest r229 of master so that you don't need to merge with 
the binary and composite changesets again.

I tried to stick to what we have discussed recently and also updated the code 
organization rationales accordingly (raimar/Documentation).

Please note that I have also converted the pair BlitzArraySlieIterator.h/tcc 
to the new style by defining the macros in a separate file which is included in 
both headers. Now the tcc scheme is consistent across the framework, but if 
you don't like this approach just leave out the last commit when you merge.

Furthermore I have added LazyDensityOperator.tcc, and converted some of the 
frees headers to Free_.h so that Free.h can bundle Free_.h (or impl/Free.tcc 
if present) together with ParsFree.h. However, I have not changed the 
interaction header files in the same way yet. Currently these are not used 
anywhere in the framework and Pars... headers are just included in the 
corresponding interaction header file, so script users have only to include 
this one header file anyway. 

Best regards
Raimar


PS: probably the testsuites are pretty much broken right now because of all 
these changes, but I could not start them to check. How do I run the tests 
with bjam again?
