• Default variables to undefined instead of raising an error
• Added test operator is that is another syntax for passing parameters to functions that have a defined signature, they must return a Boolean value. e.g.: {% if something is defined %}.
• Support {% include %} statements (Thanks to Guilherme Guerra)
• New tests added: defined, divisible
• New filters added: take (Thanks to Marko Kocić), abs, capitalize, escape (e), float, join, length, max, min, round, and title. Documentation is still ongoing, and help is wanted :)

• fix: for loop must access expression via value stack [commit]
• fix: parsing floating point numbers [commit]
