Use Vector to replace new and delete in gint，spilt gint_tools and change Makefile,remove ORB in gint

[A-006]

In MeshK, Meshcell, bigcell, meshball, and grid_technique, use vector instead of new and delete. Some parameters should be protected using private. gint_tools was spilted into 6 files,and must modify the Makefile.Objects here, otherwise there will be issues. Remove the dependency on the ORB parameter in gint; the ORB structure is not needed during the gint calculation process.

A good step. But future changes like this will need to be carefully examined for performance impact. I tried to solve the problem with some elegant class wrappers, but this had severe performance impacts on some variables.
