Performs random walk on a graph, with a restart probability of 0.7

1 | ```
randomWalk(intM, queryGenes)
``` |

`intM` |
adjacency matrix of the graph, or object of graph format containing this matrix |

`queryGenes` |
genes with which to seed the random walk |

Returns a named vector of visitation probabilities for all nodes in the graph
