ANN: Igloo 0.4.2 Released

[Joakim Karlsson]

Hi!

Igloo 0.4.2 contains the following fixes:

* We now added a missing #include <memory>, which made some compilers
fail to build Igloo.
* We've separated igloo.h into two files: igloo.h and
igloo_framework.h. If you include igloo.h you get the same behavior as
before. If you include igloo_framework.h, you can now redefine the
macros for defining Contexts. This might be useful if you find that
Igloos macros collide with names in other frameworks.

Regards,
Joakim
