* This function returns a void * representing a pointer to a valid

* parameter.
*
* Parameters:
* Filename: A char * to a NULL terminated character array, which represents
* the filename of the XML file to open, and with which to
* initialize the parser created in this function. This filename
* may also contain a path if necessary, otherwise the function
* will attempt to open a file by the name of the filename in the
* current directory of the currently running process.
*
* Returns:
* void *: Representing a pointer to a valid scew_parser structure, which
* meets the constraints of the input parameters, or NULL on error.
