Subject: Update Julia variable names
Julia supports underscores at the beginning of a variable name now. It also supports a subset of Unicode code points for the first character, and additional code points for subsequent characters.
A full explanation of all available code points was excluded as it is quite complicated and doesn't add much value in the X in Y context.
closes #516
