Create isBipartiteGraph.hpp

[THIRU-1074]

->ISSUE REFERENCE:

https://github.com/ZigRazor/CXXGraph/issues/464#issue-2491732813

->DESCRIPTION:

Implemented a header file to check if the graph is biPartite or biColourable. The algorithm has its own cycle detection algorithm which counts the number of nodes in the cycle and checks for odd nodes cycle, which determines whether the undirected graph is biPartite.

Also, check that the code compiles and runs before committing :)
