    """Reads the files given by _edgeList_ and _nodeList_ and creates a networkx graph for the files.

    This is designed only for the files produced by metaknowledge and is meant to be the reverse of [writeGraph()](#metaknowledge.graphHelpers.writeGraph), if this does not produce the desired results the networkx builtin [networkx.read_edgelist()](https://networkx.github.io/documentation/networkx-1.10/reference/generated/networkx.readwrite.edgelist.read_edgelist.html) could be tried as it is aimed at a more general usage.

    The read edge list format assumes the column named _eSource_ (default `'From'`) is the source node, then the column _eDest_ (default `'To'`) givens the destination and all other columns are attributes of the edges, e.g. weight.

    The read node list format assumes the column _idKey_ (default `'ID'`) is the ID of the node for the edge list and the resulting network. All other columns are considered attributes of the node, e.g. count.

    **Note**: If the names of the columns do not match those given to **readGraph()** a `KeyError` exception will be raised.

    **Note**: If nodes appear in the edgelist but not the nodeList they will be created silently with no attributes.
