#' Validate BioPAX files 
#' 
#' This function validates BioPAX files for errors.
#' 
#' @param inputFile a string of the name of the input BioPAX OWL file
#' @param outputFile a string of the name of the output file containing 
#'   validation results
#' @param type a string denoting the type of output: xml (default), html, biopax 
#' @param autoFix a boolean that determines if the input file should be 
#'   fixed automatically. Errors that can be automatically fixed include 
#'   generating displayName properties from names, inferring organism, and 
#'   inferring dataSource
#' @param onlyErrors a boolean of whether to only display errors
#' @param maxErrors a integer denoting the number of errors to return 
#' @param notStrict a boolean of whether to be strict in validation (default: FALSE)
#' 
#' @return an XMLInternalDocument is returned if type is set to "xml" otherwise
#'   the location of the outputfile is returned.  
#'

#'   BioPAX validator. See \url{http://biopax.baderlab.org/validator} for 
#'   additional information on validator. 
#'   See \url{http://biopax.baderlab.org/validator/errorTypes.html} for
