LabVIEW.gitignore

LabVIEW (ni.com/labview) is a graphical system design tool.
File extensions are listed here:
http://zone.ni.com/reference/en-XX/help/371361K-01/lvhowto/lv_file_extensions/
.llb and lvlibp are for binary distributions, and are excluded for the same reason shared objects are excluded.
.aliases and .lvlps are metadata related to the project file, and are automatically updated when moving between machines (see note on that help page).
