## Usage - SDK

The client object can then be instantiated and used like below. 
```
require "crobat/crobat_sdk"

client = Crobat::CrobatSDK.new("https://sonar.omnisint.io")

# Retrieving subdomains via SDK
puts(client.retrieve_subdomains("twitter.com"))

# Retrieving all results via SDK
puts(client.retrieve_all("twitter.com"))

# Retrieving tlds via SDK
puts(client.retrieve_tlds("twitter.com"))

# Retrieving reverse info for an IP via SDK
puts(client.retrieve_reverse("8.8.8.8"))

# Retrieving reverse info for an IP range via SDK
puts(client.retrieve_reverse_range("95.138.157.0/16"))
```
