CreateSubgraph: Create Subgraph
In JonnoB/PowerGridNetworking: Power-grid network simulation in R

This function creates a subgraph where the nodes which have lost links to outside the subgraph gain additional generation capacity. This generation capacity is limited to the line limits of the PowerLines. This limit prevents those lines from being overpowered, although it assumes such power is actually available

1	CreateSubgraph(g, Nodes, LineLimit = "Link.Limit")

`g`	and igraph object
`Nodes`	A character vector of node names to be in the new graph
`LineLimit`	The graph attribute name for the line limits of the network
