+ *Here we get a "pair" of data, parsed from *str, witch consists of a keyname and a keyvalue.
+ *These are written to the pointers at char **name and char **value.
+ *These pair can be in the form of:
+ *  ex1:
+ *  NAME=VALUE 
+ *      ^     ^ 
+ *      |     Here we have no delimiter this means rightDelimiterPos must be NULL
+ *      This is the left delimiter
+ *  ex2:
+ *  name(value)
+ *      ^     ^
+ *      |     This is the rightDelimiterPos and must be ')'
+ *      This is leftDelimiterPos which must be '('
+ *
+ *  Input:
+ *      char *str: the line in the form of a string where a key value pair is stored
+ *      char leftDelimiterPos: the left delimiter for example '='
+ *      char rightDelimiterPos: the right delimiter can be NULL in most cases, if NULL we assume that there is only one delimiter, which is in this case the leftDelimiterPos
+ *  Output:
+ *      char **name: The address where we store the name of the Key
+ *      char **value: The address where we store the key value
+ *      int sizeName: for size checking against memory allocated at **name
+ *      int sizeValue: for size checking against memory allocated at **value
+ *
+ *  Return:
+ *      will return NO_ERROR (0) if successfull.
+ *      If not it will return the error of the subroutine
