repository: Add a gitignore file
repository: Add default CMAKE_BUILD_TYPE

For each packages, we assign by default the Debug mode for
CMAKE_BUILD_TYPE if the CMAKE_BUILD_TYPE is empty.

We add -ggdb3 if CXX is GNU GCC and CMAKE_BUILD_TYPE equals Debug or
RelWithDebInfo and CFLAGS options -Wall -Wextra if CXX is GNU GCC.

a difference-equation model and a differential-equation model (smartgardener)
