Simon:
------
1. Added files T3, T4, T5 representing different stages of original PDF data processing. File T5 represents a set of single lines where each line is either "tree name" or "description", or "key characteristics" or "uses" or "wood" or "distribution". Some lines have extra spaces in words (due to incorrect text extraction from PDF). It is needed to pass T5 or it derivatives through spell checker to correct those words.

2. Added SQLite database template with 4 empty tables in accordance with "Misc/Database_Worksheet.pdf". Foreign keys are introduced to link tables together. Table "tree_desc" is extended to have additional attribute "full TEXT" to represent full description text.

3. Added "Misc/dbfill.sh" script to convert T4 into T5. T4, in turn, is a version of T3 without empty lines.
