XML parsing and serializing

[victorsndvg]

A future work could be the extension of the library in order of allowing the reading and writing of the parameters to an XML file.

At this point, some questions must be solved:

• Object serialization in Fortran. Only intrinsic types can be writted/readed? How we could Write/read derived types?
• Parallel IO. How we perform the parameters IO in nparallel in a scalable way? I think that the first approach could be "a single processor read/write and send data to all involved processors"

Object serialization in Fortran. Only intrinsic types can be writted/readed? How we could Write/read derived types?

Probably WriteXML and ReadXML procedures may be located in each wrapper and in the ParametesList.

Maybe a solution to Print/Serialize ParameterLists recursively is to implement an Iterator at the Dictionary hierarchy level to loop into it from the ParameterList
