Added function to search networks
Added function to check if connection is active
Added small script generating documentation
Added function to fetch network from NDEx (using getEdges()). Modifications were made to object definition (it turns out we will need to store node aliases/related terms; thus node_annot slot was added). Maybe slots for namespaces and all terms will be needed; need to discuss that
Added toy function to extract CBDD-compatible network from ndexgraph
Added possibility to reannotate nodes  when converting NDEx network to CBDD (to make the most nodes be of the same type, say gene symbol)
Added simple test script
Some more testing; fixed processing of edges
