feat: conditional_node

[ekinsenler]

conditional_node implementation with a custom condition that can be set in the node_config. Also integrated into the the existing graph for the demonstration.

[ekinsenler]

I was unable to create a more modular solution due to the requirement of state key knowledge for condition evaluation. The node must access and evaluate specific keys within the state to function correctly, particularly when parsing and evaluating complex conditions that may include built-in functions or expressions involving state variables.

Abstracting this functionality further would limit the node's ability to perform its intended purpose, as it would not have the necessary context to evaluate conditions accurately. Therefore, this implementation strikes a balance between modularity and the practical necessity of accessing state-specific information.

I welcome any suggestions on how to improve this within the constraints

ok please can you provide me an example of condition?

@ekinsenler btw I think we have implemented the depth search

[ekinsenler]

Condition can be set on node_config

{
    'key_name': 'results',
    'condition': 'len(results) > 2'
}

Or we can just set the key_name that will be checked on the state if it exists

Cool, is that already in beta?

thx, can u add it in the examples?

yes, the name is something like depth search graph

[VinciGit00]

btw @ekinsenler can u remove smart scraper cond graph and add the conditional node if a condition is present? can you do for all the graphs?

[ekinsenler]

@VinciGit00 that graph was mainly to demonstrate the usage of the conditional_node. And yes, it works on the other nodes aswell.
