Function isRelation

isRelation(property: LimeProperty): boolean
Check if a property is a relation type that links to another LimeType.

Relation types are: hasone, hasmany, belongsto, and hasandbelongstomany. These properties establish relationships between different object types in the CRM.

Use this helper to determine if a property value will be a LimeObject or array of LimeObjects rather than a simple value.
Parameters
- property: LimeProperty
  The property to check
Returns boolean
true if the property is a relation type, false otherwise
Example: Listing every property that links to another type
```
import { PlatformServiceName, isRelation } from '@limetech/lime-web-components';

const repository = platform.get(PlatformServiceName.LimeTypeRepository);
const limetype = repository.getLimeType('deal');

const relationProps = Object.values(limetype?.properties ?? {}).filter(
    isRelation
);

for (const property of relationProps) {
    const relatedType = property.relation?.getLimetype();
    console.log('Links to:', relatedType?.name);
}
```
