void	run__CODE (std::shared_ptr< tokenNode > &TKNode, const std::string &datatype)
	runs the interpreter

Private Member Functions
void	visit_controlflow (std::shared_ptr< tokenNode > &TKNode, const std::string &datatype)
	visits control flow on the syntax tree
void	visit_built_in_func (std::shared_ptr< tokenNode > &TKNode, const std::string &datatype)
	visits built in function
bool	checkCondition (std::shared_ptr< tokenNode > &TKNode, const std::string &datatype)
	checks if the condition of a control flow is true from visit_controlflow() on for-loop, while-loop, if,else if statements
void	visit_Variables (std::shared_ptr< tokenNode > &TKNode, const std::string &datatype)
	visits variable nodes and extracts their values
returnStringValues	visitWORDS (std::shared_ptr< tokenNode > &TKNode)
	attempts to figure out if the passed in argument is a StringNode, OperatorNode or VariableNode
std::string	visit__StringNode (std::shared_ptr< StringNode > &TKNode)
	visits a string and extracts it's value eg "value"
std::string	visit__StringAppendNode (std::shared_ptr< VariableNode > &nodeToAppendTo, const std::string &passedvalue)
	appends a value to the end of a variable
returnNumberValues	visitNUMBERS (std::shared_ptr< tokenNode > &TKNode)
	attempts to figure out if the passed in argument is a NumberNode, OperatorNode or VariableNode
double	visit__unaryNumberNode (std::shared_ptr< NumberNode > &TKNode)
	extracts the number value from this node which is of type unary, eg -5 or +5
double	visit__unaryNumberNodeExpr (std::shared_ptr< NumberNode > &TKNode)
	visits a number node contained within an expression such as and multiplies it by it's unary, eg -(5 + 5)
double	visit__NumberNode (std::shared_ptr< NumberNode > &TKNode)
	extracts the number value from this node , eg 5
double	visit__NumberAppendNode (std::shared_ptr< VariableNode > &nodeToAppendTo, const double &passedvalue)
	appends/adds or any other operator, a value to the end of a variable
returnNumberValues	visit__numberOPNODE (std::shared_ptr< OperatorNode > &TKNode)
	attempts to figure out which operator is being used between two number nodes
returnStringValues	visit__stringOPNODE (std::shared_ptr< OperatorNode > &TKNode)
	attempts to figure out which operator is being used between two word nodes
void	resetVariableValue (std::shared_ptr< forNode > &forobj)
	reset a variable in a for loop back to it's original value after the for loop has finished executing

Private Attributes

	name of the file currently being processed
int	lnNum
	the line number in the file which is currently being processed
bool	isInLoop
	specifies whether or not what is currently being processed is a loop or not
