Title: Fix for highlighting of digits in code block

This fixes the issue shown below - any '.' before a digit (even if it occurs in a range expression) was considered as a decimal point of the number.

I have added a custom regex as per DesignScript ATG production rules for proper identification of digits in the syntax highlighter.

@Benglin please review. Thanks.
