[Cuis] New updates: Mathematical symbols in Smalltalk code

[Juan Vuletich]

Hi Folks,

I've just pushed to GitHub quite several updates. Besides some fixes and 
enhancement to Morphic display updates, etc, the biggest news is a set 
of 32 mathematical symbols, as requested by Luciano. They can also be 
used as binary selectors, (although such code might have portability 
issues).

Clipboard copy & paste with Unicode apps work ok. For example this:
'←→↑↓ 
!"#$%&''()*+,-./0123456789:;<=>?@ABCDEFGHIJKLMNOPQRSTUVWXYZ[\]^_`abcdefghijklmnopqrstuvwxyz{|}~∀∂∃∄∅∞ℂℍℕℙℚℝℤℵ⨀⨁⨂∑∫⨕≠≡≢≣≤≥≦≧≨≩∘∙ 
¡¢£€¥Š§š©ª«¬­®¯°±²³Žµ¶·ž¹º»ŒœŸ¿ÀÁÂÃÄÅÆÇÈÉÊËÌÍÎÏÐÑÒÓÔÕÖ×ØÙÚÛÜÝÞßàáâãäåæçèéêëìíîïðñòóôõö÷øùúûüýþÿ'
is the result of evaluating
String streamContents: [ :strm | 28 to: 255 do: [ :i | strm nextPut: 
(Character value: i) ]]
and doing a simple copy / paste.

I also added some convenience methods, like 'Character forAll', 
'Character directSum' or 'Character rationalNumbers'.

When updating existing images you will be asked for recreating DejaVu 
StrikeFonts. For this to work, you need to unzip 
AdditionalFontData/DejaVuSans.zip in that folder. If you are using 
DejaVuSansMono, you need to recreate the fonts after the update.

A nice detail, suggested by Leandro Caniglia is that you can do 
'StrikeFont useRightArrow' and now the assignment is shown as 

→ . Play 
with it. It gives a new perspective on what the code is doing!

Thanks Luciano for suggesting the addition of the mathematical symbols. 
Keep tuned, next will come superscripts and subscripts.

Cheers,
Juan Vuletich
