* - changes .gitignore config file name
- updates root readme to reference to engines readme
- pushes products dataloader cleaning into product data file
- Chapter 12 is now functional and aligned with the book's points
- adds missing transformers images. Images still need to be moved to another repository
- moves random document exploration out of Collection into LTR
- SolrCollection to correctly rely on paraent search function
- SolrEngine cleans product schema
- LTR - implements exploration search function and moves collection into constructor
- LTR - renames feature attribute being return on documents

* - Ch12: All examples correct and in line with manuscript's examples
- Ch12: Fixes bug with session exploration generation
- Ch12: Removes scaling of judgment grades

* Syncs ch10, ch12 and LTR code with manuscript requirements. Fixes small bugs in ch10 related to LTR refactor

* Merges with hybrid_search, move enable_ltr function

* Chapter 14:
 - Merges cpu and gpu 3rd notebook
 - optomizes 14.5 to run batch question searches
 - Refactors several functions
 - Refactors and corrects get_query_from_question
 - Tunes/fixes question answering examples

* Ch14 small tweaks for manuscript update

* - Verifies modified chapters
- Fixes requirements broken from hybrid_search branch merge

…reygrainger#186)

* - All chapters verified, functional and consistent (See lingering issues)
- Sets Jupyter to use environment home directory instead of notebook director for execution
- Product Display: Updates templates\search-results.html product search result html rendering to have better spacing and image sizes
- Adds missing product images that emerged from removing "\N"
- SolrCollection Vector Search: De-normalize returned score to be accurate with Cos/Dot similarity
--------------------------------------------

- Ch7: Further refactors SS functions
- Ch7: Organizes and orders listings (and links/refs) from each notebook to be consistent with manuscript
- Ch7: Fixes semantic function bug and get_enrichment NRE bug
- Ch7: Adds Listing 7.14 Splade
- Ch8: Minor formatting, typo correction and cell order
- Ch9: Minor formatting, search result limit=10, and small refactorings
- Ch10: Correctly uses LTR.enable_ltr (not engine.enable_ltr)
- Ch11: Cell organization/labelling
- Ch12: Locks numpy to 1.23.5 and adds Numpy seed for consistent session synthesis
- Ch13: Cell organization, consistent result ranking, formatting, Fix 13.12 bug,
- Ch13: De-normalize vector scores from engine vector search
- Ch13: Tidy's cross-encoder code
- Ch14: Minor formatting, path corrections
------------------------------------------
Lingering issues:
- Image path: Undo hack when image is rendered from HTML (not using Jupyter Home path, using Chapter path), Fix image renderings in Ch11
- Ch7: Still needs fix for Iframe clearing 5 seconds after being rendered, verify semantic-search endpoint
- Ch12: Still 2 squirelly results. 99% consistent otherwise
- Ch13: 13.3 Amendum failing (Has been for some time?)

* Finalizes cross encoder code

… correctly in Jupyter kernel

* Properly sets root for notesbooks. --notebook-dir and .root_dir flags were not properly working

* Fix remaining path issues

* Uncomment data loading in 2.multimodal-and-hybrid-search.ipynb

* - 4.7 - listing organization
- skg.generate_request => skg.transform_request
- Fixes Ch6 bugs
- 15.18 listing organization

* - Applies listing print standards to all chapters
- Ch3. Updates print statements, organizes variable positioning
- rerank_quantity => rerank_count
- What happened to 10's feature calculater?
- Finish rerank_query refactor
- Chapter 11: Updates formatting of displaying data
- SKG: {!${defType} ...}

* SKG debug fix

* Rework ch3 tf-idf calculations; sync with manuscript

* Ch4, 5, 6: Listings and results synchronized

* Ch7 and Ch8: Listings synced

* Ch9 mostly consistent

* Syncs listing 8.1

* Ch10, Ch11 sync'd with manuscript and signed off

* Ch8 sync, ch10 n => k

* ch9: Correct, Deterministic, sync'd with manuscript, signing off

* - ch12, 13, 14, and 15 finalized and sync with Manuscript

Ch12 still has minor numeric variance.
Ch14 still uses pre-computed model

* replace -(-len(x) //  y) with math.ceil(len(x) / y) to improve readability (treygrainger#194)

* Uncomment cached model loading (like in book) so Max can debug more easily

* Formatting, organization, notes and small adjustments across codebase

* Stubbed 7.14 to fix M.2 issue
