Added the cmake folder and the cmake/Modules folder in case we need to
add some modules for the CMake configuration. In particular, we started
adding the module for the TPLs processing, together with a TPLsList.cmake
file with the list of acceptable TPLs (so far it contains only MPI).
Added a reset method for the SharedPointer, which takes a raw pointer.
Also, fixed a bug in one of the constructors, where before we set
the wrong counter.
Continuing writing the importer test. It's still basically empty. So far
we used it to check if the test directory of Panda is processed correctly
by cmake, and if all the includes/libraries are correctly installed and
usable.
