_printf Prints and formats data. The first argument it takes is a string to be printed as chars, unless a '%' is found. In that case it checks the character next to the module for it to match one of its valid identifiers. In case it matches, it calls the function function associated to the identifier character, to print the value of its corresponding argument.

	The arguments are accesed in sequential order once they recieve a valid
	identifier after the '%'.

	Returns the number of characters printed.

NAME _printf - format and print data

SYNOPSIS _printf FORMAT [ARGUMENT]...

DESCRIPTION

	Print arguments based on FORMAT. FORMAT is both a string to be printed
	and the IDENTIFIERS to call the ARGUMENT(s).

	Valid IDENTIFIERS

	%%		prints a single %

	%c		prints a char

	%s		prints a string

	%i		prints an integer

	%b		prints an int formatted into binary

	%x		formats into hex, lowercase

	%X		formats into hex, UPPERCASE

	%o		formats int into octal

	%S		prints a string with non-ascii written as hex

ARGUMENTS

	It takes many types of data as arguments, but only will print the types
	compatbile with the selected format.
	
	The program expects the user to match the type of the identifier with the
	type of the argument passed, and for them to be in the order they are from
	the identifiers. 

NONSTANDARD BEHAVIOUR

	If the FORMAT string contains more identifiers than the amount of 
	arguments it's passed, it will return error "-1";.

	If the function it's passed more arguments than identifiers 
	in the string, extra arguments are ignored.

	If an identifier its passed any other argument type than its expected type
	it falls into undefined behaviour (It will mostly break or print s***).

	If the last character of the string is a %, returns error "-1".
