Created basic R package structure
Moved all files to the repository root folder; edited DESCRIPTION
First version of function for establishing NDEx connection and user authentication using RCurl
Ready to start work on network retrieval!
Edited man page for the package; added obvious dependencies (RCurl, RJSONIO - maybe replaced later with another JSON parser, igraph)
Added function which are present in the package so far to namespace
Added simple S4 class for network representation and validator function for it. So far we just ask it to have node and edge data frames; with at least 1 column for nodes and 2 for edges
Added 'roxygenized' documentation (NAMESPACE updated automatically by roxygen2)
Established system with internal environment in a package (a placeholder for stuff like authorization options of RCurl, which are of no value to user). Objects in this environment are intended to be used only by package functions and will not be visible in globalenv
Added functions to get/set/store the host URL (they will be needed in queries anyway)
Added basic utilities for GET, POST and PUT queries to the API
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
Described current progress in README.md
