///////////////////////////////////////////////////////////////////////////////////////
// Start of template parsing
///////////////////////////////////////////////////////////////////////////////////////
// How to:
// There are two cases how templates are build
// - only values
// {{convert|original_value|original_unit|conversion_unit|round_to|...}}
// - key and value as a pair connected by "="
// {{height|first_unit=first_value|second_unit=second_value|...}}
// The first value after "{{" is the templateName and every "|" will result in a new
// PropertyNode of the TemplateNode. The $childrenChilds[][] array contains the
// TextNodes of these children.
// With $childrenChilds[0][0]->getText() you get the text from the first TextNode of
// the first PropertyNode. For example:
// {{convert|ORIGINAL_VALUE|original_unit|conversion_unit|round_to|...}} or
// {{height|first_unit=FIRST_VALUE|second_unit=second_value|...}}
// With $childrenChilds[1][0]->getText() you get the text from the first TextNode
// of the second PropertyNode.
// With $childrenChilds[0][0]->getParent()->getKey() you get the key of the first
// PropertyNode. For example:
// {{height|FIRST_UNIT=first_value|second_unit=second_value|...}}
// The first case (convert template example) has no key.
