=== Version 1.006 (2024-03-20)

    examples/*.pl
    Add ability to read an ENV environmental variable 'PDF_prefLib' to get
      the preferred library to use (API2 or Builder). Checks for command line
      A or B (or -A -B), ENV{PDF_prefLib} A or B, PDF::API2 or PDF::Builder,
      examples/PDFpref file A or B, PDF::API2 or PDF::Builder. This is of
      real interest only when BOTH libraries are installed, and you need to
      pick one or the other to run with.

      Note that util/3_examples.pl also has the ability to give 'A' or 'B'
      on the command line to indicate a preference for API2 or Builder (if
      both are installed).

      Note that the t-tests use a dummy library PDFAPI2Mock, that provides
      enough of the interface to let the tests be run, regardless of whether
      you already have API2 or Builder installed! However, you will still need
      to have at least one of the two installed in order to run the examples
      or otherwise use PDF::Table.

    lib/PDF/Table.pm, examples/no_repeat.pl (new), util/3_examples
    Was incorrectly defaulting undefined header repeat switch, in a manner
      that did not allow the switch to be '0': no repeating the header (#77).
      Add new example of multipage table without repeating header.

    README.md  update to point to new Home Page structure on catskilltech.com
      including both full documentation and examples
