Description

This PR adds data type inference to the XML format plugin.  In similar fashion to other plugins, it adds a new configuration parameter: allTextMode, which when set to true, reads all data as strings.  The default is true.

Note that the inference is limited to doubles, date, timestamps, boolean and strings.
