* Add new OCR sample. Also, update markdown. * Sample organization. Some samples never actually made their way into the main solution file. Reorganize things a bit so it's easier to review sample names. Remove ancient WebApplication sample which isn't really relevant anymore. * Add to test-samples. * Add a link for Documentation and re-label the existing link API Reference --------- Co-authored-by: Joseph Argento <[email protected]> Co-authored-by: datalogics-saharay <[email protected]> Co-authored-by: Rob Lyman <[email protected]> Co-authored-by: Robert Boehne <[email protected]>
