Add a new Linux comand input type to accept LEF/DEF files
1) New flag -ldp -ld etc. Put LEF/DEF files at the very last of command input. Example command: -bash-4.2$ ./LayoutAnalyzer -ldp net2s_m3_alone.gds examples/net2s.sim_input test.spef confidential/asap7/aes_cipher_top.def confidential/asap7/asap7sc7p5t_24_L_4x_170912_mod.lef confidential/asap7/asap7sc7p5t_24_R_4x_170912_mod.lef confidential/asap7/asap7sc7p5t_24_SL_4x_170912_mod.lef confidential/asap7/asap7sc7p5t_24_SRAM_4x_170912_mod.lef 2) Called functions to read LEF/DEF and to generate auto ports from LEF/DEF. Main credit to Michael.
