Brand new Nemeth edit table supporting production of "UEB with Nemeth…
…" documents Adds support for UEB literary texts containing Nemeth blocks for technical content. Nemeth switch indicators are applied to mark the beginning and end of each math block, so one can always distinguish between literary text and technical content. Handles a range of punctuation, grouping and other symbols and their spacing around the math blocks. Use nemeth_edit_en_ueb_with_switch_indicators.ctb as editTable along with en-ueb-g1.ctb or en-ueb-g2.ctb as mathtextTable.

| #liblouisutdml inserts a space before and after each math block to separate it from the literary text. | ||
| #Such spaces are often undesirable, e.g., for punctuation and grouping symbols around the math blocks. | ||
| #In many cases these signs do not take their most appropriate forms as the math blocks | ||
| #are not yet present at the stage of literary Braille translation. | ||
| #This table makes a limited attempt to reconstruct the most likely form of some of the signs | ||
| #directly preceding or following a math block and to decide which of the automatically added spaces | ||
| #are to be kept or removed. | ||
