parseURI function

Parse a URI string into its elements

This breaks a URI given as a string into its different elements such as protocol/scheme, host, port, file name, query. This information can be used, for example, when constructing URIs relative to a base URI.

The return value is an S3-style object of class URI.

This function uses libxml routines to perform the parsing.
