Lohit Odia 2.91.0 ready for testing under Lohit 2 project

   Started working on this in last month with Shilpa. When initial started working on this script, found it bit difficult. But Odia script is very similar with Devanagari and over the time found comfort with it.

   Shilpa did most of the work and i did verification and fixed few issues. One thing again i noticed during release is using of AFDKO. It is good and we should use AFDKO fully in Lohit project for better quality. Will see if we can do it in long term.

  For now regarding 2.91.0 release. Following are important points:

• Followed Unicode specifications.
  
• Re-writing all GSUB rules.
• Open type rules are available in .fea file for easy re-usability.
• Feature file compiled with AFDKO.
• Supports 'orya' and 'ory2' opentype specifications tag.
  
• Developer friendly glyphs names with AGL syntax format.
• Corrected glyph class for all glyphs. 
• Improved shape of ka-viramasignodia-taodia.
• Added Glyph positioning rules for below based matras.
• Test file available with release tarball.
• Auto testing support with harfbuzz hb-shape.Tested with Harfbuzz and Uniscribe (W8 and XP)

   Update Lohit project page for information regarding download. During release i found few issues which are noted in TODO file. Will fix them before next release. If you find any issue do report on github. Also note TTF file available on my fedorapeople page.

   I remember in FUEL conference i got some improvement suggestions. Couple of them were related to adding Latin to Odia fonts. Presently dont have resource for same but looking forward to solve it in future.
