ndi_install

  NDI_INSTALL - install the NDI distribution and its ancillary directories

      B = NDI_INSTALL

  Installs the GitHub distributions necessary to run NDI-matlab.
  These are installed at [USERPATH filesep 'tools']
     (for example, /Users/steve/Documents/MATLAB/tools/)

  The startup file is edited to add a startup procedure in VHTOOLS.

  One can also dictate a different install directory by passing a full pathname:

  B = NDI_INSTALL(PATHNAME)

  PATHNAME should not include any shell script shortcuts (like '~').

  Finally, one can also install either the minimal set of tools needed for NDI
  (DEPENDENCIES=1), or one can install the standard VHTOOLS suite (DEPENDENCIES=2).
  For developers, the option DEPENDENCIES=3 will install dependencies based
  on the locally checked out branch of NDI-matlab.

  B = NDI_INSTALL(PATHNAME, DEPENDENCIES)

  If PATHNAME is blank, then the default pathway of [USERPATH filesep 'tools'] is used.
