Notes:
 Variables are either all upper case letters (e.g., "ABC") or any character apart from "]" enclosed by "[" and "]" (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 '#'.
 Semicolons (';') 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 'yyyyMMdd' or 'yyyyMMdd HH:mm:ss'
 times have to be of format 'HH:mm:ss' or 'yyyyMMdd HH:mm:ss'
 the characters in square brackets in function names are optional:
e.g.
