[igraph] Checking whether graph g1 is a subgraph of graph g2

[Kamran Soomro]

Hi,  

I am new to igraph and would love any help you guys can give me. I want to 
check whether a particular graph g1 is a subgraph of another graph g2. Please 
note that this is not a subgraph polymorphism problem. I do not want to know if 
g1 is a polymorphic subgraph of g2. I want the result to be true if and only if 
the vertex and edge labels of g1 also match with a subgraph in g2. How do I 
achieve this with igraph? Thanks!
