GraphIO provides support to [LightGraphs.jl](https://github.com/JuliaGraphs/LightGraphs.jl) for reading/writing graphs in various formats.

Currently, the following functionality is provided:

Format        | Read | Write | Multiple Graphs| Format Name  |
--------------|------|-------|----------------|--------------|
[EdgeList]    |   ✓  |  ✓    |                |EdgeListFormat|
[GML]         |   ✓  |  ✓    | ✓              |GMLFormat     |
[Graph6]      |   ✓  |  ✓    | ✓              |Graph6Format  |
[GraphML]     |   ✓  |  ✓    | ✓              |GraphMLFormat |
[Pajek NET]   |   ✓  |  ✓    |                |NETFormat     |
[GEXF]        |      |  ✓    |                |GEXFFormat    |
[DOT]         |   ✓  |       | ✓              |DOTFormat     |
[CDF]         |   ✓  |       |                |CDFFormat     |

[EdgeList]: a simple list of sources and dests separated by whitespace and/or comma, one pair per line.

Graphs are read using either the `loadgraph` function or, for formats that support multiple graphs in a single file,
the `loadgraphs` functions. `loadgraph` returns a LightGraph object, while `loadgraphs` returns a dictionary of LightGraph objects.  

For example, an edgelist file could be loaded as:

```
graph = loadgraph("path_to_graph/my_edgelist.txt", "graph_key", EdgeListFormat())
```
