Implement resource type AWS::EC2::RouteTable

AWS::EC2::RouteTable
http://docs.amazonwebservices.com/AWSCloudFormation/latest/UserGuide/aws-resource-ec2-route-table.html
Creates a new route table within a VPC. After you create a new route table, you can add routes and associate the table with a subnet.
Your VPC has an implicit router (represented by the R enclosed in a circle in the diagrams in this guide).
Your VPC automatically comes with a modifiable main route table.
You can create other route tables in your VPC (for the limit on the number you can create, see Appendix B: Limits).
You can replace the main route table with a custom table you've created (if you want a different table to be the default table each new subnet is associated with).

Parameters
VpcId

Comments
According to the route table documentation:
http://docs.amazonwebservices.com/AmazonVPC/latest/UserGuide/VPC_Route_Tables.html
a VPC comes with a default main route table.
AWS::EC2::RouteTable is for specifying additional route tables to associate with subnets. Every subnet must be associated with a route table.
Whereas in Quantum, a router is not associated with a network, only subnets. This also means that a network does not have a default router assigned.
