Resources Zome

Steps to create this zome:

0. Delete boilerplate zome

1. Define a Resource entry and add it to the entry_defs

#[hdk_entry(id = "resource")]
struct Resource {
    owner_pub_key: AgentPubKey,
    name: String,
}

entry_defs![Resource::entry_def()];

2. Add the create_resource function that:

   1. Receives the name of the resource.
   2. Gets the public key of the executing agent with agent_info.
   3. Creates the resource with create_entry.
   4. Creates a link between the public key and the entry hash (using hash_entry and create_link).

3. Add the get_my_resources function that:

   1. Gets the public key of the executing agent with agent_info.
   2. Does a get_links with the public key as the base.
   3. For each target hash, performs a get to get the contents of the Resource entry.
   4. Returns the list of resources.

4. Add the validation functions for the links and the resources:

#[hdk_extern]
fn validate_create_entry_resource(data: ValidationData) -> ExternResult<ValidationCallbackResult> {
    ...
}

#[hdk_extern]
fn validate_link(data: ValidationData) -> ExternResult<ValidationCallbackResult> {
    ...
}
