Notes:
- Variables are either all alphanumeric and _, starting with uppercase letter (e.g., "ABc_12"),
any character apart from "]" enclosed by "[" and "]" (e.g., "[Hello World]") or
enclosed by single quotes (e.g., "'Hello World'").
- 'start' and 'end' for function 'substr' are indices that start at 1.
- Index 'end' for function 'substr' is excluded (like Java's 'String.substring(int,int)' method)
- Line comments start with '#'.
- Semi-colons (';') or commas (',') can be used as separator in the formulas,
e.g., 'pow(2,2)' is equivalent to 'pow(2;2)'
- dates have to be of format 'yyyy-MM-dd' or 'yyyy-MM-dd HH:mm:ss'
- times have to be of format 'HH:mm:ss' or 'yyyy-MM-dd HH:mm:ss'
- the characters in square brackets in function names are optional:
e.g.MathematicalExpressionText Wrapper for a String object to be editable in the GOE.
