Working unfold code with test case (SrVO3), initial version
Added utility (preprocess) to create unfold.map from two POSCAR files.
Fixed spectrum output (divided by proper k-space ratio) and tool to extend hamiltonian to a supercell (to be used with doping tool).
Use correct weight for spectrum, fixing the output problem; added hamiltonian extention tool.
Removed unnecessary large files
Force to ignore testing case data
