added gui functionality

Closes #8

See merge request research/Utils/IPcoreGenerator!2

added mkdirs before running tests, so that verilog-library file can be retrieved before running tests.

moved generated files (v, mpd, pao) to correct folder, as specified in the documentation and goldenmodel folder

bugfix: HDL was always set as output path; it should have been configurable via model.getOuputPath() & properties file

corrected typo error in <<assign m_axis_1aclk=user_clk;>> should have been: <<assign m_axis_1_aclk=user_clk;>>
