/** @page pg_validationkit_guideline Validation Kit Coding Guidelines
*
* The guidelines extends the VBox coding guidelines (@ref pg_vbox_guideline)
* and currently only defines python prefixes and linting.
*
*
* @section sec_validationkit_guideline_python Python
*
* Python is a typeless language so using prefixes to indicate the intended
* type of a variable or attribute can be very helpful.
*
* Type prefixes:
* - 'b' for byte (octect).
* - 'ch' for a single character.
* - 'f' for boolean and flags.
* - 'fn' for function or method references.
* - 'fp' for floating point values.
* - 'i' for integers.
* - 'l' for long integers.
* - 'o' for objects, structures and anything with attributes that doesn't
* match any of the other type prefixes.
* - 'r' for a range or xrange.
* - 's' for a string (can be unicode).
* - 'su' for a unicode string when the distinction is important.
*
* Collection qualifiers:
* - 'a' for a list or an array.
* - 'd' for a dictionary.
* - 'h' for a hash.
* - 't' for a tuple.
*
* Other qualifiers:
* - 'c' for a count. Implies integer or long integer type. Higest
* priority.
* - 'sec' for a second value. Implies long integer type.
* - 'ms' for a millisecond value. Implies long integer type.
* - 'us' for a microsecond value. Implies long integer type.
* - 'ns' for a nanosecond value. Implies long integer type.
*
* The 'ms', 'us', 'ns' and 'se' qualifiers can be capitalized when prefixed by
* 'c', e.g. cMsElapsed. While this technically means they are no longer a
* prefix, it's easier to read and everyone understands what it means.
*
* The type collection qualifiers comes first, then the other qualifiers and
* finally the type qualifier.
*
* Python statements are terminated by semicolons (';') as a convention.
