New patches submitted from eg123 for the automatization of the configuration process. Use of pkg-config to find dolfin and eigen3 includes and libs * src/Makefile.in: make variables (CPPFLAGS, LDFLAGS, LIBS) are defined substituting the Autoconf ones * src/configure.ac: dolfin and eigen3 compile and link flags are looked for through pkg-config macros * DESCRIPTION: added pkg-config as a build-dependency configure fails if dependencies are not met.

1) Improve the feval
2) Add the possibility to use the 'normal' for BC
3) Add wrapper for subdomain (It should be enough to modify SubSpace)
