   'Inserts blocks in AutoCAD using data - insertion point, block name/full path, scale factors, rotation angle - from Excel.
   'Note that the block name or the block path must already exists, otherwise nothing will be inserted.
   'The code uses late binding, so no reference to external AutoCAD (type) library is required.
   'It goes without saying that AutoCAD must be installed at your computer before running this code.
