V0.7.2

• Added German translation. There is still more work to do on this, but I'm told it is usable.
• Added Norwegian translation
• Improved reading of "neuter" units
• Changed some character wording ("if and only if", "implies", "triangle")
• Fix problems with the zip files and regional variants. This should allow en-gb and zh-tw to be available.
• Fixed bugs in navigating in character mode and simple mode.
• Changed the names of some characters to be more semantic (e.g., "long double left right arrow" is not "if and only if").
• Add some "literal" (not semantic) names for characters for LiteralSpeak and navigation.
• Fixed some bugs dealing with "intent"
• Fix a bug with generating id's that could cause a crash once every 36^4 times
• Add another heuristic to prevent something from being a potential function (when the potential function name appears within the argument)
• Fixed reading of a degree symbol followed by "F" or "C".
• Corrected the rule for what is allowed for "intent"
• Improved the inference rules for units (supports "mi" if it is marked as "normal")
• Fixed a navigation bug with log, ln, and lg
• Improved error messages -- these should aid in reporting problems in speech and navigation
• Improved speech for fractions that involve units ("meters per second")
• Many improvements to the recognition of Chemistry
• Fixed a Nemeth bug where a script end and baseline indicator were emitted when neither should have been present.
• Added varepsilon character to UEB
• Fixed off-by-one error when computing what to highlight in braille.
• Add definitions for "ⅆ", "ⅇ", "ⅈ" to braille codes
