Included "stringified expressions" which look like normal expression but are interpreted as strings. Examples are
<< /var/log/boing.txt
symbol::myTagWhichIsAString
Added the stringified identifiers to the symbol parsing.
Suppressed all warnings in the output file that's created by jflex
Fixed slot regex for Association which can have the form #foo where foo cannot start with a number, but with letters or $ and after the first letter a combination of letters, numbers and $ is allowed.
Fixed that the rhs of >> and >>> is really parsed as expression so that the behavior is more like what you would expect from MMA
New plugin built for testing
Moved all parser messages to a properties file and improved many of them.
Made Association limiters like braces so that the matching counter part is highlighted .
Slots are no symbols anymore but they are highlighted when in context of a anonymous function
Separated association slots #foo from others and gave them a separate AST element type
 MessageName PsiElements can now return their symbol, tag and language
 Split parsing of Slots from parsing of symbols
 Improved smart completion when inside Message[..]
