public class SetManyVariables

implements VariableUpdater
```
Sets the values of the variables whenever a token passes through, but does not use the token's value.
Optionally, the specified values can be expanded, in case it is made up of variables itself.

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. 'len("abc")' is the same as 'length("abc")'
- 'str' uses java.text.DecimalFormat when supplying a format string

A lot of the functions have been modeled after LibreOffice:
https://help.libreoffice.org/Calc/Functions_by_Category

Additional functions:
- env(String): String
   First argument is the name of the environment variable to retrieve.
   The result is the value of the environment variable.

Additional procedures:
- println(...)
   One or more arguments are printed as comma-separated list to stdout.
   If no argument is provided, a simple line feed is output.
