This function takes a partition manager, a filename and a filter
as arguments. The filename is used to create names for dot file
generated by this function. There is one file per dimension.
Each file contain the graph (in dot format) of interprocess
relation in between entities of a given dimension. The interprocess
relation are coming from provided partition manager information.
Graph node are node, edge or face described by there address,
there id, there type. Directed edge show the counterpart of
an entity on remote process.

The integer filter argument may remove graph with entity that have only
less than "filter" remotes ones. Typically if filter=1 all 1 to 1 graph
will be removed and only graph of entities related to more then 1 remote
will be kept.

Dot graph format is recognized by "dot"  graphviz application. For
example:
dot -Tpng -o pm_1.png 0_filename
will create a png picture pm_1.png from outputted 0_filename (node
entities relationship).
