1. Information
--------------

Formats cvars and vstrs, using format strings.  Optionally joins 2 strings.

Format:
s = string
i = integer number
f = float number

varFormat uses the "format specifiers" shown above (s, i, f) to change a string.  Format specifiers are used to indicate the variable type and variable length of the variable that you are changing.

To use the format specifiers, indicate a number and a format type.  You can precede the number with a "0" to indicate that the variable you are changing should be prefixed with a "0"s to "fill out" the length of the string.

So, using:
6i  would mean that the variable you are formatting will be an integer, at most 6 characters long.
06i would mean taht the variable you are formatting will be an integer, and will always be 6 characters long, and prefixed with 0s if necessary.

2. Usage Examples
-----------------

\varFormat user_float1 2.2f 98.765 // sets var to 98.76

\varFormat user_int1 06i 987 // sets var to 000987

\varFormat user_string1 s Demo 06i 987 // sets var to Demo000987

\set chInfoNum 108                       // sets chInfoNum to 108 (date in YYYYMMDD format)
\varFormat user_string2 s Demo i $chInfo // sets var to DemoYYYYMMDD (today's date)

3. Immediate Var Updates
------------------------

*** WARNING/IMPORTANT: There is a delay between issuing a console command to q3, and the actual command being executed.  This means that changing a var with varMath may be delayed.  There is a way around this issue: prefix all of your user created vars with "user_".  This will tell the system that these vars should be updated as soon as possible.

Example of a delay (using varMath):
-----------------------------------
We want to create a string to contain the mapname and a number afterwards (q3dm17_1)

\set MyNumber "0"     // MyNumber = 0
\varMath MyNumber+ 1; varMath MyDemoNam = $mapname + _ + $MyNumber // MyDemoName = q3dm17_0, we wanted q3dm17_1

Now, what we want is "q3dm17_1".  But, because of the delay in updating MyNumber, we get "q3dm17_0", since MyNumber is late in getting updated, the next call to varMath uses MyNumber with the value of "0", when we wanted "1" to be used.

Solution:
---------
If we use the "user_" prefix for the vars we create, varMath will update these vars immediately (no delay) and we can use these values in subsequent calls to varMath, etc.

\set user_MyNumber "0"     // user_MyNumber = 0
\varMath user_MyNumber + 1; varMath user_MyDemoName = $mapname + _ + $user_MyNumber // user_MyDemoName = q3dm17_1, exactly what we wanted
